+The `acceleratedmobilepageurl1` command-line interface *(CLI)* allows to use most features of the *Google acceleratedmobilepageurl* service from the comfort of your terminal.
+
+By default all output is printed to standard out, but flags can be set to direct it into a file independent of your shell's
+capabilities. Errors will be printed to standard error, and cause the program's exit code to be non-zero.
+
+If data-structures are requested, these will be returned as pretty-printed JSON, to be useful as input to other tools.
+
+Everything else about the *acceleratedmobilepageurl* API can be found at the
+[official documentation site](https://developers.google.com/amp/cache/).
+
+# Installation and Source Code
+
+Install the command-line interface with cargo using:
+
+```bash
+cargo install google-acceleratedmobilepageurl1-cli
+```
+
+Find the source code [on github](https://github.com/Byron/google-apis-rs/tree/master/gen/acceleratedmobilepageurl1-cli).
+
+# Usage
+
+This documentation was generated from the *acceleratedmobilepageurl* API at revision *20171202*. The CLI is at version *1.0.7*.
+
+```bash
+acceleratedmobilepageurl1 [options]
+        amp-urls
+                batch-get (-r <kv>)... [-p <v>]... [-o <out>]
+  acceleratedmobilepageurl1 --help
+
+Configuration:
+  --config-dir <folder>
+            A directory into which we will store our persistent data. Defaults to
+            a user-writable directory that we will create during the first invocation.
+            [default: ~/.google-service-cli]
+  --debug
+            Output all server communication to standard error. `tx` and `rx` are placed
+            into the same stream.
+  --debug-auth
+            Output all communication related to authentication to standard error. `tx`
+            and `rx` are placed into the same stream.
+
+```
+
+# Configuration
+
+The program will store all persistent data in the `~/.google-service-cli` directory in *JSON* files prefixed with `acceleratedmobilepageurl1-`.  You can change the directory used to store configuration with the `--config-dir` flag on a per-invocation basis.
+
+More information about the various kinds of persistent data are given in the following paragraphs.
+
+# Authentication
+
+Most APIs require a user to authenticate any request. If this is the case, the [scope][scopes] determines the 
+set of permissions granted. The granularity of these is usually no more than *read-only* or *full-access*.
+
+If not set, the system will automatically select the smallest feasible scope, e.g. when invoking a
+method that is read-only, it will ask only for a read-only scope. 
+You may use the `--scope` flag to specify a scope directly. 
+All applicable scopes are documented in the respective method's CLI documentation.
+
+The first time a scope is used, the user is asked for permission. Follow the instructions given 
+by the CLI to grant permissions, or to decline.
+
+If a scope was authenticated by the user, the respective information will be stored as *JSON* in the configuration
+directory, e.g. `~/.google-service-cli/acceleratedmobilepageurl1-token-<scope-hash>.json`. No manual management of these tokens
+is necessary.
+
+To revoke granted authentication, please refer to the [official documentation][revoke-access].
+
+# Application Secrets
+
+In order to allow any application to use Google services, it will need to be registered using the 
+[Google Developer Console][google-dev-console]. APIs the application may use are then enabled for it
+one by one. Most APIs can be used for free and have a daily quota.
+
+To allow more comfortable usage of the CLI without forcing anyone to register an own application, the CLI
+comes with a default application secret that is configured accordingly. This also means that heavy usage
+all around the world may deplete the daily quota.
+
+You can workaround this limitation by putting your own secrets file at this location: 
+`~/.google-service-cli/acceleratedmobilepageurl1-secret.json`, assuming that the required *acceleratedmobilepageurl* API 
+was enabled for it. Such a secret file can be downloaded in the *Google Developer Console* at 
+*APIs & auth -> Credentials -> Download JSON* and used as is.
+
+Learn more about how to setup Google projects and enable APIs using the [official documentation][google-project-new].
+
+
+# Debugging
+
+Even though the CLI does its best to provide usable error messages, sometimes it might be desirable to know
+what exactly led to a particular issue. This is done by allowing all client-server communication to be 
+output to standard error *as-is*.
+
+The `--debug` flag will print all client-server communication to standard error, whereas the `--debug-auth` flag
+will cause all communication related to authentication to standard error.
+If the `--debug` flag is set, error-results will be debug-printed, possibly yielding more information about the 
+issue at hand.
+
+You may consider redirecting standard error into a file for ease of use, e.g. `acceleratedmobilepageurl1 --debug <resource> <method> [options] 2>debug.txt`.

+The `google-acceleratedmobilepageurl1` library allows access to all features of the *Google acceleratedmobilepageurl* service.
+
+This documentation was generated from *acceleratedmobilepageurl* crate version *1.0.7+20171202*, where *20171202* is the exact revision of the *acceleratedmobilepageurl:v1* schema built by the [mako](http://www.makotemplates.org/) code generator *v1.0.7*.
+
+Everything else about the *acceleratedmobilepageurl* *v1* API can be found at the
+[official documentation site](https://developers.google.com/amp/cache/).
+# Features
+
+Handle the following *Resources* with ease from the central [hub](https://docs.rs/google-acceleratedmobilepageurl1/1.0.7+20171202/google_acceleratedmobilepageurl1/struct.Acceleratedmobilepageurl.html) ... 
+
+* [amp urls](https://docs.rs/google-acceleratedmobilepageurl1/1.0.7+20171202/google_acceleratedmobilepageurl1/struct.AmpUrl.html)
+ * [*batch get*](https://docs.rs/google-acceleratedmobilepageurl1/1.0.7+20171202/google_acceleratedmobilepageurl1/struct.AmpUrlBatchGetCall.html)
+
+
+
+
+# Structure of this Library
+
+The API is structured into the following primary items:
+
+* **[Hub](https://docs.rs/google-acceleratedmobilepageurl1/1.0.7+20171202/google_acceleratedmobilepageurl1/struct.Acceleratedmobilepageurl.html)**
+    * a central object to maintain state and allow accessing all *Activities*
+    * creates [*Method Builders*](https://docs.rs/google-acceleratedmobilepageurl1/1.0.7+20171202/google_acceleratedmobilepageurl1/trait.MethodsBuilder.html) which in turn
+      allow access to individual [*Call Builders*](https://docs.rs/google-acceleratedmobilepageurl1/1.0.7+20171202/google_acceleratedmobilepageurl1/trait.CallBuilder.html)
+* **[Resources](https://docs.rs/google-acceleratedmobilepageurl1/1.0.7+20171202/google_acceleratedmobilepageurl1/trait.Resource.html)**
+    * primary types that you can apply *Activities* to
+    * a collection of properties and *Parts*
+    * **[Parts](https://docs.rs/google-acceleratedmobilepageurl1/1.0.7+20171202/google_acceleratedmobilepageurl1/trait.Part.html)**
+        * a collection of properties
+        * never directly used in *Activities*
+* **[Activities](https://docs.rs/google-acceleratedmobilepageurl1/1.0.7+20171202/google_acceleratedmobilepageurl1/trait.CallBuilder.html)**
+    * operations to apply to *Resources*
+
+All *structures* are marked with applicable traits to further categorize them and ease browsing.
+
+Generally speaking, you can invoke *Activities* like this:
+
+```Rust,ignore
+let r = hub.resource().activity(...).doit()
+```
+
+Or specifically ...
+
+```ignore
+let r = hub.amp_urls().batch_get(...).doit()
+```
+
+The `resource()` and `activity(...)` calls create [builders][builder-pattern]. The second one dealing with `Activities` 
+supports various methods to configure the impending operation (not shown here). It is made such that all required arguments have to be 
+specified right away (i.e. `(...)`), whereas all optional ones can be [build up][builder-pattern] as desired.
+The `doit()` method performs the actual communication with the server and returns the respective result.
+
+# Usage
+
+## Setting up your Project
+
+To use this library, you would put the following lines into your `Cargo.toml` file:
+
+```toml
+[dependencies]
+google-acceleratedmobilepageurl1 = "*"
+```
+
+## A complete example
+
+```Rust
+extern crate hyper;
+extern crate hyper_rustls;
+extern crate yup_oauth2 as oauth2;
+extern crate google_acceleratedmobilepageurl1 as acceleratedmobilepageurl1;
+use acceleratedmobilepageurl1::BatchGetAmpUrlsRequest;
+use acceleratedmobilepageurl1::{Result, Error};
+use std::default::Default;
+use oauth2::{Authenticator, DefaultAuthenticatorDelegate, ApplicationSecret, MemoryStorage};
+use acceleratedmobilepageurl1::Acceleratedmobilepageurl;
+
+// Get an ApplicationSecret instance by some means. It contains the `client_id` and 
+// `client_secret`, among other things.
+let secret: ApplicationSecret = Default::default();
+// Instantiate the authenticator. It will choose a suitable authentication flow for you, 
+// unless you replace  `None` with the desired Flow.
+// Provide your own `AuthenticatorDelegate` to adjust the way it operates and get feedback about 
+// what's going on. You probably want to bring in your own `TokenStorage` to persist tokens and
+// retrieve them from storage.
+let auth = Authenticator::new(&secret, DefaultAuthenticatorDelegate,
+                              hyper::Client::with_connector(hyper::net::HttpsConnector::new(hyper_rustls::TlsClient::new())),
+                              <MemoryStorage as Default>::default(), None);
+let mut hub = Acceleratedmobilepageurl::new(hyper::Client::with_connector(hyper::net::HttpsConnector::new(hyper_rustls::TlsClient::new())), auth);
+// As the method needs a request, you would usually fill it with the desired information
+// into the respective structure. Some of the parts shown here might not be applicable !
+// Values shown here are possibly random and not representative !
+let mut req = BatchGetAmpUrlsRequest::default();
+
+// You can configure optional parameters by calling the respective setters at will, and
+// execute the final call using `doit()`.
+// Values shown here are possibly random and not representative !
+let result = hub.amp_urls().batch_get(req)
+             .doit();
+
+match result {
+    Err(e) => match e {
+        // The Error enum provides details about what exactly happened.
+        // You can also just use its `Debug`, `Display` or `Error` traits
+         Error::HttpError(_)
+        |Error::MissingAPIKey
+        |Error::MissingToken(_)
+        |Error::Cancelled
+        |Error::UploadSizeLimitExceeded(_, _)
+        |Error::Failure(_)
+        |Error::BadRequest(_)
+        |Error::FieldClash(_)
+        |Error::JsonDecodeError(_, _) => println!("{}", e),
+    },
+    Ok(res) => println!("Success: {:?}", res),
+}
+
+```
+## Handling Errors
+
+All errors produced by the system are provided either as [Result](https://docs.rs/google-acceleratedmobilepageurl1/1.0.7+20171202/google_acceleratedmobilepageurl1/enum.Result.html) enumeration as return value of 
+the doit() methods, or handed as possibly intermediate results to either the 
+[Hub Delegate](https://docs.rs/google-acceleratedmobilepageurl1/1.0.7+20171202/google_acceleratedmobilepageurl1/trait.Delegate.html), or the [Authenticator Delegate](https://docs.rs/yup-oauth2/*/yup_oauth2/trait.AuthenticatorDelegate.html).
+
+When delegates handle errors or intermediate values, they may have a chance to instruct the system to retry. This 
+makes the system potentially resilient to all kinds of errors.
+
+## Uploads and Downloads
+If a method supports downloads, the response body, which is part of the [Result](https://docs.rs/google-acceleratedmobilepageurl1/1.0.7+20171202/google_acceleratedmobilepageurl1/enum.Result.html), should be
+read by you to obtain the media.
+If such a method also supports a [Response Result](https://docs.rs/google-acceleratedmobilepageurl1/1.0.7+20171202/google_acceleratedmobilepageurl1/trait.ResponseResult.html), it will return that by default.
+You can see it as meta-data for the actual media. To trigger a media download, you will have to set up the builder by making
+this call: `.param("alt", "media")`.
+
+Methods supporting uploads can do so using up to 2 different protocols: 
+*simple* and *resumable*. The distinctiveness of each is represented by customized 
+`doit(...)` methods, which are then named `upload(...)` and `upload_resumable(...)` respectively.
+
+## Customization and Callbacks
+
+You may alter the way an `doit()` method is called by providing a [delegate](https://docs.rs/google-acceleratedmobilepageurl1/1.0.7+20171202/google_acceleratedmobilepageurl1/trait.Delegate.html) to the 
+[Method Builder](https://docs.rs/google-acceleratedmobilepageurl1/1.0.7+20171202/google_acceleratedmobilepageurl1/trait.CallBuilder.html) before making the final `doit()` call. 
+Respective methods will be called to provide progress information, as well as determine whether the system should 
+retry on failure.
+
+The [delegate trait](https://docs.rs/google-acceleratedmobilepageurl1/1.0.7+20171202/google_acceleratedmobilepageurl1/trait.Delegate.html) is default-implemented, allowing you to customize it with minimal effort.
+
+## Optional Parts in Server-Requests
+
+All structures provided by this library are made to be [enocodable](https://docs.rs/google-acceleratedmobilepageurl1/1.0.7+20171202/google_acceleratedmobilepageurl1/trait.RequestValue.html) and 
+[decodable](https://docs.rs/google-acceleratedmobilepageurl1/1.0.7+20171202/google_acceleratedmobilepageurl1/trait.ResponseResult.html) via *json*. Optionals are used to indicate that partial requests are responses 
+are valid.
+Most optionals are are considered [Parts](https://docs.rs/google-acceleratedmobilepageurl1/1.0.7+20171202/google_acceleratedmobilepageurl1/trait.Part.html) which are identifiable by name, which will be sent to 
+the server to indicate either the set parts of the request or the desired parts in the response.
+
+## Builder Arguments
+
+Using [method builders](https://docs.rs/google-acceleratedmobilepageurl1/1.0.7+20171202/google_acceleratedmobilepageurl1/trait.CallBuilder.html), you are able to prepare an action call by repeatedly calling it's methods.
+These will always take a single argument, for which the following statements are true.
+
+* [PODs][wiki-pod] are handed by copy
+* strings are passed as `&str`
+* [request values](https://docs.rs/google-acceleratedmobilepageurl1/1.0.7+20171202/google_acceleratedmobilepageurl1/trait.RequestValue.html) are moved
+

+
+//! This documentation was generated from *acceleratedmobilepageurl* crate version *1.0.7+20171202*, where *20171202* is the exact revision of the *acceleratedmobilepageurl:v1* schema built by the [mako](http://www.makotemplates.org/) code generator *v1.0.7*.
+//! 
+//! Everything else about the *acceleratedmobilepageurl* *v1* API can be found at the
+//! [official documentation site](https://developers.google.com/amp/cache/).
+//! The original source code is [on github](https://github.com/Byron/google-apis-rs/tree/master/gen/acceleratedmobilepageurl1).
+//! # Features
+//! 
+//! Handle the following *Resources* with ease from the central [hub](struct.Acceleratedmobilepageurl.html) ... 
+//! 
+//! * [amp urls](struct.AmpUrl.html)
+//!  * [*batch get*](struct.AmpUrlBatchGetCall.html)
+//! 
+//! 
+//! 
+//! 
+//! Not what you are looking for ? Find all other Google APIs in their Rust [documentation index](http://byron.github.io/google-apis-rs).
+//! 
+//! # Structure of this Library
+//! 
+//! The API is structured into the following primary items:
+//! 
+//! * **[Hub](struct.Acceleratedmobilepageurl.html)**
+//!     * a central object to maintain state and allow accessing all *Activities*
+//!     * creates [*Method Builders*](trait.MethodsBuilder.html) which in turn
+//!       allow access to individual [*Call Builders*](trait.CallBuilder.html)
+//! * **[Resources](trait.Resource.html)**
+//!     * primary types that you can apply *Activities* to
+//!     * a collection of properties and *Parts*
+//!     * **[Parts](trait.Part.html)**
+//!         * a collection of properties
+//!         * never directly used in *Activities*
+//! * **[Activities](trait.CallBuilder.html)**
+//!     * operations to apply to *Resources*
+//! 
+//! All *structures* are marked with applicable traits to further categorize them and ease browsing.
+//! 
+//! Generally speaking, you can invoke *Activities* like this:
+//! 
+//! ```Rust,ignore
+//! let r = hub.resource().activity(...).doit()
+//! ```
+//! 
+//! Or specifically ...
+//! 
+//! ```ignore
+//! let r = hub.amp_urls().batch_get(...).doit()
+//! ```
+//! 
+//! The `resource()` and `activity(...)` calls create [builders][builder-pattern]. The second one dealing with `Activities` 
+//! supports various methods to configure the impending operation (not shown here). It is made such that all required arguments have to be 
+//! specified right away (i.e. `(...)`), whereas all optional ones can be [build up][builder-pattern] as desired.
+//! The `doit()` method performs the actual communication with the server and returns the respective result.
+//! 
+//! # Usage
+//! 
+//! ## Setting up your Project
+//! 
+//! To use this library, you would put the following lines into your `Cargo.toml` file:
+//! 
+//! ```toml
+//! [dependencies]
+//! google-acceleratedmobilepageurl1 = "*"
+//! ```
+//! 
+//! ## A complete example
+//! 
+//! ```test_harness,no_run
+//! extern crate hyper;
+//! extern crate hyper_rustls;
+//! extern crate yup_oauth2 as oauth2;
+//! extern crate google_acceleratedmobilepageurl1 as acceleratedmobilepageurl1;
+//! use acceleratedmobilepageurl1::BatchGetAmpUrlsRequest;
+//! use acceleratedmobilepageurl1::{Result, Error};
+//! # #[test] fn egal() {
+//! use std::default::Default;
+//! use oauth2::{Authenticator, DefaultAuthenticatorDelegate, ApplicationSecret, MemoryStorage};
+//! use acceleratedmobilepageurl1::Acceleratedmobilepageurl;
+//! 
+//! // Get an ApplicationSecret instance by some means. It contains the `client_id` and 
+//! // `client_secret`, among other things.
+//! let secret: ApplicationSecret = Default::default();
+//! // Instantiate the authenticator. It will choose a suitable authentication flow for you, 
+//! // unless you replace  `None` with the desired Flow.
+//! // Provide your own `AuthenticatorDelegate` to adjust the way it operates and get feedback about 
+//! // what's going on. You probably want to bring in your own `TokenStorage` to persist tokens and
+//! // retrieve them from storage.
+//! let auth = Authenticator::new(&secret, DefaultAuthenticatorDelegate,
+//!                               hyper::Client::with_connector(hyper::net::HttpsConnector::new(hyper_rustls::TlsClient::new())),
+//!                               <MemoryStorage as Default>::default(), None);
+//! let mut hub = Acceleratedmobilepageurl::new(hyper::Client::with_connector(hyper::net::HttpsConnector::new(hyper_rustls::TlsClient::new())), auth);
+//! // As the method needs a request, you would usually fill it with the desired information
+//! // into the respective structure. Some of the parts shown here might not be applicable !
+//! // Values shown here are possibly random and not representative !
+//! let mut req = BatchGetAmpUrlsRequest::default();
+//! 
+//! // You can configure optional parameters by calling the respective setters at will, and
+//! // execute the final call using `doit()`.
+//! // Values shown here are possibly random and not representative !
+//! let result = hub.amp_urls().batch_get(req)
+//!              .doit();
+//! 
+//! match result {
+//!     Err(e) => match e {
+//!         // The Error enum provides details about what exactly happened.
+//!         // You can also just use its `Debug`, `Display` or `Error` traits
+//!          Error::HttpError(_)
+//!         |Error::MissingAPIKey
+//!         |Error::MissingToken(_)
+//!         |Error::Cancelled
+//!         |Error::UploadSizeLimitExceeded(_, _)
+//!         |Error::Failure(_)
+//!         |Error::BadRequest(_)
+//!         |Error::FieldClash(_)
+//!         |Error::JsonDecodeError(_, _) => println!("{}", e),
+//!     },
+//!     Ok(res) => println!("Success: {:?}", res),
+//! }
+//! # }
+//! ```
+//! ## Handling Errors
+//! 
+//! All errors produced by the system are provided either as [Result](enum.Result.html) enumeration as return value of 
+//! the doit() methods, or handed as possibly intermediate results to either the 
+//! [Hub Delegate](trait.Delegate.html), or the [Authenticator Delegate](https://docs.rs/yup-oauth2/*/yup_oauth2/trait.AuthenticatorDelegate.html).
+//! 
+//! When delegates handle errors or intermediate values, they may have a chance to instruct the system to retry. This 
+//! makes the system potentially resilient to all kinds of errors.
+//! 
+//! ## Uploads and Downloads
+//! If a method supports downloads, the response body, which is part of the [Result](enum.Result.html), should be
+//! read by you to obtain the media.
+//! If such a method also supports a [Response Result](trait.ResponseResult.html), it will return that by default.
+//! You can see it as meta-data for the actual media. To trigger a media download, you will have to set up the builder by making
+//! this call: `.param("alt", "media")`.
+//! 
+//! Methods supporting uploads can do so using up to 2 different protocols: 
+//! *simple* and *resumable*. The distinctiveness of each is represented by customized 
+//! `doit(...)` methods, which are then named `upload(...)` and `upload_resumable(...)` respectively.
+//! 
+//! ## Customization and Callbacks
+//! 
+//! You may alter the way an `doit()` method is called by providing a [delegate](trait.Delegate.html) to the 
+//! [Method Builder](trait.CallBuilder.html) before making the final `doit()` call. 
+//! Respective methods will be called to provide progress information, as well as determine whether the system should 
+//! retry on failure.
+//! 
+//! The [delegate trait](trait.Delegate.html) is default-implemented, allowing you to customize it with minimal effort.
+//! 
+//! ## Optional Parts in Server-Requests
+//! 
+//! All structures provided by this library are made to be [enocodable](trait.RequestValue.html) and 
+//! [decodable](trait.ResponseResult.html) via *json*. Optionals are used to indicate that partial requests are responses 
+//! are valid.
+//! Most optionals are are considered [Parts](trait.Part.html) which are identifiable by name, which will be sent to 
+//! the server to indicate either the set parts of the request or the desired parts in the response.
+//! 
+//! ## Builder Arguments
+//! 
+//! Using [method builders](trait.CallBuilder.html), you are able to prepare an action call by repeatedly calling it's methods.
+//! These will always take a single argument, for which the following statements are true.
+//! 
+//! * [PODs][wiki-pod] are handed by copy
+//! * strings are passed as `&str`
+//! * [request values](trait.RequestValue.html) are moved
+//! 
+//! Arguments will always be copied or cloned into the builder, to make them independent of their original life times.
+//!

+The `adexchangebuyer2-v2-beta1` command-line interface *(CLI)* allows to use most features of the *Google AdExchangeBuyerII* service from the comfort of your terminal.
+
+By default all output is printed to standard out, but flags can be set to direct it into a file independent of your shell's
+capabilities. Errors will be printed to standard error, and cause the program's exit code to be non-zero.
+
+If data-structures are requested, these will be returned as pretty-printed JSON, to be useful as input to other tools.
+
+Everything else about the *AdExchangeBuyerII* API can be found at the
+[official documentation site](https://developers.google.com/ad-exchange/buyer-rest/reference/rest/).
+
+# Installation and Source Code
+
+Install the command-line interface with cargo using:
+
+```bash
+cargo install google-adexchangebuyer2_v2_beta1-cli
+```
+
+Find the source code [on github](https://github.com/Byron/google-apis-rs/tree/master/gen/adexchangebuyer2_v2_beta1-cli).
+
+# Usage
+
+This documentation was generated from the *AdExchangeBuyerII* API at revision *20171208*. The CLI is at version *1.0.7*.

+
+Configuration:
+  [--scope <url>]...
+            Specify the authentication a method should be executed in. Each scope
+            requires the user to grant this application permission to use it.
+            If unset, it defaults to the shortest scope url for a particular method.
+  --config-dir <folder>
+            A directory into which we will store our persistent data. Defaults to
+            a user-writable directory that we will create during the first invocation.
+            [default: ~/.google-service-cli]
+  --debug
+            Output all server communication to standard error. `tx` and `rx` are placed
+            into the same stream.
+  --debug-auth
+            Output all communication related to authentication to standard error. `tx`
+            and `rx` are placed into the same stream.
+
+```
+
+# Configuration
+
+The program will store all persistent data in the `~/.google-service-cli` directory in *JSON* files prefixed with `adexchangebuyer2-v2-beta1-`.  You can change the directory used to store configuration with the `--config-dir` flag on a per-invocation basis.
+
+More information about the various kinds of persistent data are given in the following paragraphs.
+
+# Authentication
+
+Most APIs require a user to authenticate any request. If this is the case, the [scope][scopes] determines the 
+set of permissions granted. The granularity of these is usually no more than *read-only* or *full-access*.
+
+If not set, the system will automatically select the smallest feasible scope, e.g. when invoking a
+method that is read-only, it will ask only for a read-only scope. 
+You may use the `--scope` flag to specify a scope directly. 
+All applicable scopes are documented in the respective method's CLI documentation.
+
+The first time a scope is used, the user is asked for permission. Follow the instructions given 
+by the CLI to grant permissions, or to decline.
+
+If a scope was authenticated by the user, the respective information will be stored as *JSON* in the configuration
+directory, e.g. `~/.google-service-cli/adexchangebuyer2-v2-beta1-token-<scope-hash>.json`. No manual management of these tokens
+is necessary.
+
+To revoke granted authentication, please refer to the [official documentation][revoke-access].
+
+# Application Secrets
+
+In order to allow any application to use Google services, it will need to be registered using the 
+[Google Developer Console][google-dev-console]. APIs the application may use are then enabled for it
+one by one. Most APIs can be used for free and have a daily quota.
+
+To allow more comfortable usage of the CLI without forcing anyone to register an own application, the CLI
+comes with a default application secret that is configured accordingly. This also means that heavy usage
+all around the world may deplete the daily quota.
+
+You can workaround this limitation by putting your own secrets file at this location: 
+`~/.google-service-cli/adexchangebuyer2-v2-beta1-secret.json`, assuming that the required *adexchangebuyer2* API 
+was enabled for it. Such a secret file can be downloaded in the *Google Developer Console* at 
+*APIs & auth -> Credentials -> Download JSON* and used as is.
+
+Learn more about how to setup Google projects and enable APIs using the [official documentation][google-project-new].
+
+
+# Debugging
+
+Even though the CLI does its best to provide usable error messages, sometimes it might be desirable to know
+what exactly led to a particular issue. This is done by allowing all client-server communication to be 
+output to standard error *as-is*.
+
+The `--debug` flag will print all client-server communication to standard error, whereas the `--debug-auth` flag
+will cause all communication related to authentication to standard error.
+If the `--debug` flag is set, error-results will be debug-printed, possibly yielding more information about the 
+issue at hand.
+
+You may consider redirecting standard error into a file for ease of use, e.g. `adexchangebuyer2-v2-beta1 --debug <resource> <method> [options] 2>debug.txt`.

+The `analyticsreporting4` command-line interface *(CLI)* allows to use most features of the *Google AnalyticsReporting* service from the comfort of your terminal.
+
+By default all output is printed to standard out, but flags can be set to direct it into a file independent of your shell's
+capabilities. Errors will be printed to standard error, and cause the program's exit code to be non-zero.
+
+If data-structures are requested, these will be returned as pretty-printed JSON, to be useful as input to other tools.
+
+Everything else about the *AnalyticsReporting* API can be found at the
+[official documentation site](https://developers.google.com/analytics/devguides/reporting/core/v4/).
+
+# Installation and Source Code
+
+Install the command-line interface with cargo using:
+
+```bash
+cargo install google-analyticsreporting4-cli
+```
+
+Find the source code [on github](https://github.com/Byron/google-apis-rs/tree/master/gen/analyticsreporting4-cli).
+
+# Usage
+
+This documentation was generated from the *AnalyticsReporting* API at revision *20171108*. The CLI is at version *1.0.7*.
+
+```bash
+analyticsreporting4 [options]
+        reports
+                batch-get (-r <kv>)... [-p <v>]... [-o <out>]
+  analyticsreporting4 --help
+
+Configuration:
+  [--scope <url>]...
+            Specify the authentication a method should be executed in. Each scope
+            requires the user to grant this application permission to use it.
+            If unset, it defaults to the shortest scope url for a particular method.
+  --config-dir <folder>
+            A directory into which we will store our persistent data. Defaults to
+            a user-writable directory that we will create during the first invocation.
+            [default: ~/.google-service-cli]
+  --debug
+            Output all server communication to standard error. `tx` and `rx` are placed
+            into the same stream.
+  --debug-auth
+            Output all communication related to authentication to standard error. `tx`
+            and `rx` are placed into the same stream.
+
+```
+
+# Configuration
+
+The program will store all persistent data in the `~/.google-service-cli` directory in *JSON* files prefixed with `analyticsreporting4-`.  You can change the directory used to store configuration with the `--config-dir` flag on a per-invocation basis.
+
+More information about the various kinds of persistent data are given in the following paragraphs.
+
+# Authentication
+
+Most APIs require a user to authenticate any request. If this is the case, the [scope][scopes] determines the 
+set of permissions granted. The granularity of these is usually no more than *read-only* or *full-access*.
+
+If not set, the system will automatically select the smallest feasible scope, e.g. when invoking a
+method that is read-only, it will ask only for a read-only scope. 
+You may use the `--scope` flag to specify a scope directly. 
+All applicable scopes are documented in the respective method's CLI documentation.
+
+The first time a scope is used, the user is asked for permission. Follow the instructions given 
+by the CLI to grant permissions, or to decline.
+
+If a scope was authenticated by the user, the respective information will be stored as *JSON* in the configuration
+directory, e.g. `~/.google-service-cli/analyticsreporting4-token-<scope-hash>.json`. No manual management of these tokens
+is necessary.
+
+To revoke granted authentication, please refer to the [official documentation][revoke-access].
+
+# Application Secrets
+
+In order to allow any application to use Google services, it will need to be registered using the 
+[Google Developer Console][google-dev-console]. APIs the application may use are then enabled for it
+one by one. Most APIs can be used for free and have a daily quota.
+
+To allow more comfortable usage of the CLI without forcing anyone to register an own application, the CLI
+comes with a default application secret that is configured accordingly. This also means that heavy usage
+all around the world may deplete the daily quota.
+
+You can workaround this limitation by putting your own secrets file at this location: 
+`~/.google-service-cli/analyticsreporting4-secret.json`, assuming that the required *analyticsreporting* API 
+was enabled for it. Such a secret file can be downloaded in the *Google Developer Console* at 
+*APIs & auth -> Credentials -> Download JSON* and used as is.
+
+Learn more about how to setup Google projects and enable APIs using the [official documentation][google-project-new].
+
+
+# Debugging
+
+Even though the CLI does its best to provide usable error messages, sometimes it might be desirable to know
+what exactly led to a particular issue. This is done by allowing all client-server communication to be 
+output to standard error *as-is*.
+
+The `--debug` flag will print all client-server communication to standard error, whereas the `--debug-auth` flag
+will cause all communication related to authentication to standard error.
+If the `--debug` flag is set, error-results will be debug-printed, possibly yielding more information about the 
+issue at hand.
+
+You may consider redirecting standard error into a file for ease of use, e.g. `analyticsreporting4 --debug <resource> <method> [options] 2>debug.txt`.

+The `google-analyticsreporting4` library allows access to all features of the *Google AnalyticsReporting* service.
+
+This documentation was generated from *AnalyticsReporting* crate version *1.0.7+20171108*, where *20171108* is the exact revision of the *analyticsreporting:v4* schema built by the [mako](http://www.makotemplates.org/) code generator *v1.0.7*.
+
+Everything else about the *AnalyticsReporting* *v4* API can be found at the
+[official documentation site](https://developers.google.com/analytics/devguides/reporting/core/v4/).
+# Features
+
+Handle the following *Resources* with ease from the central [hub](https://docs.rs/google-analyticsreporting4/1.0.7+20171108/google_analyticsreporting4/struct.AnalyticsReporting.html) ... 
+
+* [reports](https://docs.rs/google-analyticsreporting4/1.0.7+20171108/google_analyticsreporting4/struct.Report.html)
+ * [*batch get*](https://docs.rs/google-analyticsreporting4/1.0.7+20171108/google_analyticsreporting4/struct.ReportBatchGetCall.html)
+
+
+
+
+# Structure of this Library
+
+The API is structured into the following primary items:
+
+* **[Hub](https://docs.rs/google-analyticsreporting4/1.0.7+20171108/google_analyticsreporting4/struct.AnalyticsReporting.html)**
+    * a central object to maintain state and allow accessing all *Activities*
+    * creates [*Method Builders*](https://docs.rs/google-analyticsreporting4/1.0.7+20171108/google_analyticsreporting4/trait.MethodsBuilder.html) which in turn
+      allow access to individual [*Call Builders*](https://docs.rs/google-analyticsreporting4/1.0.7+20171108/google_analyticsreporting4/trait.CallBuilder.html)
+* **[Resources](https://docs.rs/google-analyticsreporting4/1.0.7+20171108/google_analyticsreporting4/trait.Resource.html)**
+    * primary types that you can apply *Activities* to
+    * a collection of properties and *Parts*
+    * **[Parts](https://docs.rs/google-analyticsreporting4/1.0.7+20171108/google_analyticsreporting4/trait.Part.html)**
+        * a collection of properties
+        * never directly used in *Activities*
+* **[Activities](https://docs.rs/google-analyticsreporting4/1.0.7+20171108/google_analyticsreporting4/trait.CallBuilder.html)**
+    * operations to apply to *Resources*
+
+All *structures* are marked with applicable traits to further categorize them and ease browsing.
+
+Generally speaking, you can invoke *Activities* like this:
+
+```Rust,ignore
+let r = hub.resource().activity(...).doit()
+```
+
+Or specifically ...
+
+```ignore
+let r = hub.reports().batch_get(...).doit()
+```
+
+The `resource()` and `activity(...)` calls create [builders][builder-pattern]. The second one dealing with `Activities` 
+supports various methods to configure the impending operation (not shown here). It is made such that all required arguments have to be 
+specified right away (i.e. `(...)`), whereas all optional ones can be [build up][builder-pattern] as desired.
+The `doit()` method performs the actual communication with the server and returns the respective result.
+
+# Usage
+
+## Setting up your Project
+
+To use this library, you would put the following lines into your `Cargo.toml` file:
+
+```toml
+[dependencies]
+google-analyticsreporting4 = "*"
+```
+
+## A complete example
+
+```Rust
+extern crate hyper;
+extern crate hyper_rustls;
+extern crate yup_oauth2 as oauth2;
+extern crate google_analyticsreporting4 as analyticsreporting4;
+use analyticsreporting4::GetReportsRequest;
+use analyticsreporting4::{Result, Error};
+use std::default::Default;
+use oauth2::{Authenticator, DefaultAuthenticatorDelegate, ApplicationSecret, MemoryStorage};
+use analyticsreporting4::AnalyticsReporting;
+
+// Get an ApplicationSecret instance by some means. It contains the `client_id` and 
+// `client_secret`, among other things.
+let secret: ApplicationSecret = Default::default();
+// Instantiate the authenticator. It will choose a suitable authentication flow for you, 
+// unless you replace  `None` with the desired Flow.
+// Provide your own `AuthenticatorDelegate` to adjust the way it operates and get feedback about 
+// what's going on. You probably want to bring in your own `TokenStorage` to persist tokens and
+// retrieve them from storage.
+let auth = Authenticator::new(&secret, DefaultAuthenticatorDelegate,
+                              hyper::Client::with_connector(hyper::net::HttpsConnector::new(hyper_rustls::TlsClient::new())),
+                              <MemoryStorage as Default>::default(), None);
+let mut hub = AnalyticsReporting::new(hyper::Client::with_connector(hyper::net::HttpsConnector::new(hyper_rustls::TlsClient::new())), auth);
+// As the method needs a request, you would usually fill it with the desired information
+// into the respective structure. Some of the parts shown here might not be applicable !
+// Values shown here are possibly random and not representative !
+let mut req = GetReportsRequest::default();
+
+// You can configure optional parameters by calling the respective setters at will, and
+// execute the final call using `doit()`.
+// Values shown here are possibly random and not representative !
+let result = hub.reports().batch_get(req)
+             .doit();
+
+match result {
+    Err(e) => match e {
+        // The Error enum provides details about what exactly happened.
+        // You can also just use its `Debug`, `Display` or `Error` traits
+         Error::HttpError(_)
+        |Error::MissingAPIKey
+        |Error::MissingToken(_)
+        |Error::Cancelled
+        |Error::UploadSizeLimitExceeded(_, _)
+        |Error::Failure(_)
+        |Error::BadRequest(_)
+        |Error::FieldClash(_)
+        |Error::JsonDecodeError(_, _) => println!("{}", e),
+    },
+    Ok(res) => println!("Success: {:?}", res),
+}
+
+```
+## Handling Errors
+
+All errors produced by the system are provided either as [Result](https://docs.rs/google-analyticsreporting4/1.0.7+20171108/google_analyticsreporting4/enum.Result.html) enumeration as return value of 
+the doit() methods, or handed as possibly intermediate results to either the 
+[Hub Delegate](https://docs.rs/google-analyticsreporting4/1.0.7+20171108/google_analyticsreporting4/trait.Delegate.html), or the [Authenticator Delegate](https://docs.rs/yup-oauth2/*/yup_oauth2/trait.AuthenticatorDelegate.html).
+
+When delegates handle errors or intermediate values, they may have a chance to instruct the system to retry. This 
+makes the system potentially resilient to all kinds of errors.
+
+## Uploads and Downloads
+If a method supports downloads, the response body, which is part of the [Result](https://docs.rs/google-analyticsreporting4/1.0.7+20171108/google_analyticsreporting4/enum.Result.html), should be
+read by you to obtain the media.
+If such a method also supports a [Response Result](https://docs.rs/google-analyticsreporting4/1.0.7+20171108/google_analyticsreporting4/trait.ResponseResult.html), it will return that by default.
+You can see it as meta-data for the actual media. To trigger a media download, you will have to set up the builder by making
+this call: `.param("alt", "media")`.
+
+Methods supporting uploads can do so using up to 2 different protocols: 
+*simple* and *resumable*. The distinctiveness of each is represented by customized 
+`doit(...)` methods, which are then named `upload(...)` and `upload_resumable(...)` respectively.
+
+## Customization and Callbacks
+
+You may alter the way an `doit()` method is called by providing a [delegate](https://docs.rs/google-analyticsreporting4/1.0.7+20171108/google_analyticsreporting4/trait.Delegate.html) to the 
+[Method Builder](https://docs.rs/google-analyticsreporting4/1.0.7+20171108/google_analyticsreporting4/trait.CallBuilder.html) before making the final `doit()` call. 
+Respective methods will be called to provide progress information, as well as determine whether the system should 
+retry on failure.
+
+The [delegate trait](https://docs.rs/google-analyticsreporting4/1.0.7+20171108/google_analyticsreporting4/trait.Delegate.html) is default-implemented, allowing you to customize it with minimal effort.
+
+## Optional Parts in Server-Requests
+
+All structures provided by this library are made to be [enocodable](https://docs.rs/google-analyticsreporting4/1.0.7+20171108/google_analyticsreporting4/trait.RequestValue.html) and 
+[decodable](https://docs.rs/google-analyticsreporting4/1.0.7+20171108/google_analyticsreporting4/trait.ResponseResult.html) via *json*. Optionals are used to indicate that partial requests are responses 
+are valid.
+Most optionals are are considered [Parts](https://docs.rs/google-analyticsreporting4/1.0.7+20171108/google_analyticsreporting4/trait.Part.html) which are identifiable by name, which will be sent to 
+the server to indicate either the set parts of the request or the desired parts in the response.
+
+## Builder Arguments
+
+Using [method builders](https://docs.rs/google-analyticsreporting4/1.0.7+20171108/google_analyticsreporting4/trait.CallBuilder.html), you are able to prepare an action call by repeatedly calling it's methods.
+These will always take a single argument, for which the following statements are true.
+
+* [PODs][wiki-pod] are handed by copy
+* strings are passed as `&str`
+* [request values](https://docs.rs/google-analyticsreporting4/1.0.7+20171108/google_analyticsreporting4/trait.RequestValue.html) are moved
+
+Arguments will always be copied or cloned into the builder, to make them independent of their original life times.

+The `cloudbuild1` command-line interface *(CLI)* allows to use most features of the *Google Cloud Build* service from the comfort of your terminal.
+
+By default all output is printed to standard out, but flags can be set to direct it into a file independent of your shell's
+capabilities. Errors will be printed to standard error, and cause the program's exit code to be non-zero.
+
+If data-structures are requested, these will be returned as pretty-printed JSON, to be useful as input to other tools.
+
+Everything else about the *Cloud Build* API can be found at the
+[official documentation site](https://cloud.google.com/container-builder/docs/).
+
+# Installation and Source Code
+
+Install the command-line interface with cargo using:
+
+```bash
+cargo install google-cloudbuild1-cli
+```
+
+Find the source code [on github](https://github.com/Byron/google-apis-rs/tree/master/gen/cloudbuild1-cli).
+
+# Usage
+
+This documentation was generated from the *Cloud Build* API at revision *20171205*. The CLI is at version *1.0.7*.
+
+```bash
+cloudbuild1 [options]
+        operations
+                cancel <name> (-r <kv>)... [-p <v>]... [-o <out>]
+                get <name> [-p <v>]... [-o <out>]

+  cloudbuild1 --help
+
+Configuration:
+  [--scope <url>]...
+            Specify the authentication a method should be executed in. Each scope
+            requires the user to grant this application permission to use it.
+            If unset, it defaults to the shortest scope url for a particular method.
+  --config-dir <folder>
+            A directory into which we will store our persistent data. Defaults to
+            a user-writable directory that we will create during the first invocation.
+            [default: ~/.google-service-cli]
+  --debug
+            Output all server communication to standard error. `tx` and `rx` are placed
+            into the same stream.
+  --debug-auth
+            Output all communication related to authentication to standard error. `tx`
+            and `rx` are placed into the same stream.
+
+```
+
+# Configuration
+
+The program will store all persistent data in the `~/.google-service-cli` directory in *JSON* files prefixed with `cloudbuild1-`.  You can change the directory used to store configuration with the `--config-dir` flag on a per-invocation basis.
+
+More information about the various kinds of persistent data are given in the following paragraphs.
+
+# Authentication
+
+Most APIs require a user to authenticate any request. If this is the case, the [scope][scopes] determines the 
+set of permissions granted. The granularity of these is usually no more than *read-only* or *full-access*.
+
+If not set, the system will automatically select the smallest feasible scope, e.g. when invoking a
+method that is read-only, it will ask only for a read-only scope. 
+You may use the `--scope` flag to specify a scope directly. 
+All applicable scopes are documented in the respective method's CLI documentation.
+
+The first time a scope is used, the user is asked for permission. Follow the instructions given 
+by the CLI to grant permissions, or to decline.
+
+If a scope was authenticated by the user, the respective information will be stored as *JSON* in the configuration
+directory, e.g. `~/.google-service-cli/cloudbuild1-token-<scope-hash>.json`. No manual management of these tokens
+is necessary.
+
+To revoke granted authentication, please refer to the [official documentation][revoke-access].
+
+# Application Secrets
+
+In order to allow any application to use Google services, it will need to be registered using the 
+[Google Developer Console][google-dev-console]. APIs the application may use are then enabled for it
+one by one. Most APIs can be used for free and have a daily quota.
+
+To allow more comfortable usage of the CLI without forcing anyone to register an own application, the CLI
+comes with a default application secret that is configured accordingly. This also means that heavy usage
+all around the world may deplete the daily quota.
+
+You can workaround this limitation by putting your own secrets file at this location: 
+`~/.google-service-cli/cloudbuild1-secret.json`, assuming that the required *cloudbuild* API 
+was enabled for it. Such a secret file can be downloaded in the *Google Developer Console* at 
+*APIs & auth -> Credentials -> Download JSON* and used as is.
+
+Learn more about how to setup Google projects and enable APIs using the [official documentation][google-project-new].
+
+
+# Debugging
+
+Even though the CLI does its best to provide usable error messages, sometimes it might be desirable to know
+what exactly led to a particular issue. This is done by allowing all client-server communication to be 
+output to standard error *as-is*.
+
+The `--debug` flag will print all client-server communication to standard error, whereas the `--debug-auth` flag
+will cause all communication related to authentication to standard error.
+If the `--debug` flag is set, error-results will be debug-printed, possibly yielding more information about the 
+issue at hand.
+
+You may consider redirecting standard error into a file for ease of use, e.g. `cloudbuild1 --debug <resource> <method> [options] 2>debug.txt`.

+The `google-cloudbuild1` library allows access to all features of the *Google Cloud Build* service.
+
+This documentation was generated from *Cloud Build* crate version *1.0.7+20171205*, where *20171205* is the exact revision of the *cloudbuild:v1* schema built by the [mako](http://www.makotemplates.org/) code generator *v1.0.7*.
+
+Everything else about the *Cloud Build* *v1* API can be found at the
+[official documentation site](https://cloud.google.com/container-builder/docs/).
+# Features
+
+Handle the following *Resources* with ease from the central [hub](https://docs.rs/google-cloudbuild1/1.0.7+20171205/google_cloudbuild1/struct.CloudBuild.html) ...

+
+# Structure of this Library
+
+The API is structured into the following primary items:
+
+* **[Hub](https://docs.rs/google-cloudbuild1/1.0.7+20171205/google_cloudbuild1/struct.CloudBuild.html)**
+    * a central object to maintain state and allow accessing all *Activities*
+    * creates [*Method Builders*](https://docs.rs/google-cloudbuild1/1.0.7+20171205/google_cloudbuild1/trait.MethodsBuilder.html) which in turn
+      allow access to individual [*Call Builders*](https://docs.rs/google-cloudbuild1/1.0.7+20171205/google_cloudbuild1/trait.CallBuilder.html)
+* **[Resources](https://docs.rs/google-cloudbuild1/1.0.7+20171205/google_cloudbuild1/trait.Resource.html)**
+    * primary types that you can apply *Activities* to
+    * a collection of properties and *Parts*
+    * **[Parts](https://docs.rs/google-cloudbuild1/1.0.7+20171205/google_cloudbuild1/trait.Part.html)**
+        * a collection of properties
+        * never directly used in *Activities*
+* **[Activities](https://docs.rs/google-cloudbuild1/1.0.7+20171205/google_cloudbuild1/trait.CallBuilder.html)**
+    * operations to apply to *Resources*
+
+All *structures* are marked with applicable traits to further categorize them and ease browsing.
+
+Generally speaking, you can invoke *Activities* like this:
+
+```Rust,ignore
+let r = hub.resource().activity(...).doit()
+```
+
+Or specifically ...
+
+```ignore
+let r = hub.operations().cancel(...).doit()
+let r = hub.projects().triggers_run(...).doit()
+let r = hub.projects().builds_create(...).doit()
+let r = hub.operations().list(...).doit()
+let r = hub.operations().get(...).doit()
+let r = hub.projects().builds_retry(...).doit()
+```
+
+The `resource()` and `activity(...)` calls create [builders][builder-pattern]. The second one dealing with `Activities` 
+supports various methods to configure the impending operation (not shown here). It is made such that all required arguments have to be 
+specified right away (i.e. `(...)`), whereas all optional ones can be [build up][builder-pattern] as desired.
+The `doit()` method performs the actual communication with the server and returns the respective result.
+
+# Usage
+
+## Setting up your Project
+
+To use this library, you would put the following lines into your `Cargo.toml` file:
+
+```toml
+[dependencies]
+google-cloudbuild1 = "*"
+```
+
+## A complete example
+
+```Rust
+extern crate hyper;
+extern crate hyper_rustls;
+extern crate yup_oauth2 as oauth2;
+extern crate google_cloudbuild1 as cloudbuild1;
+use cloudbuild1::{Result, Error};
+use std::default::Default;
+use oauth2::{Authenticator, DefaultAuthenticatorDelegate, ApplicationSecret, MemoryStorage};
+use cloudbuild1::CloudBuild;
+
+// Get an ApplicationSecret instance by some means. It contains the `client_id` and 
+// `client_secret`, among other things.
+let secret: ApplicationSecret = Default::default();
+// Instantiate the authenticator. It will choose a suitable authentication flow for you, 
+// unless you replace  `None` with the desired Flow.
+// Provide your own `AuthenticatorDelegate` to adjust the way it operates and get feedback about 
+// what's going on. You probably want to bring in your own `TokenStorage` to persist tokens and
+// retrieve them from storage.
+let auth = Authenticator::new(&secret, DefaultAuthenticatorDelegate,
+                              hyper::Client::with_connector(hyper::net::HttpsConnector::new(hyper_rustls::TlsClient::new())),
+                              <MemoryStorage as Default>::default(), None);
+let mut hub = CloudBuild::new(hyper::Client::with_connector(hyper::net::HttpsConnector::new(hyper_rustls::TlsClient::new())), auth);
+// You can configure optional parameters by calling the respective setters at will, and
+// execute the final call using `doit()`.

+## Handling Errors
+
+All errors produced by the system are provided either as [Result](https://docs.rs/google-cloudbuild1/1.0.7+20171205/google_cloudbuild1/enum.Result.html) enumeration as return value of 
+the doit() methods, or handed as possibly intermediate results to either the 
+[Hub Delegate](https://docs.rs/google-cloudbuild1/1.0.7+20171205/google_cloudbuild1/trait.Delegate.html), or the [Authenticator Delegate](https://docs.rs/yup-oauth2/*/yup_oauth2/trait.AuthenticatorDelegate.html).
+
+When delegates handle errors or intermediate values, they may have a chance to instruct the system to retry. This 
+makes the system potentially resilient to all kinds of errors.
+
+## Uploads and Downloads
+If a method supports downloads, the response body, which is part of the [Result](https://docs.rs/google-cloudbuild1/1.0.7+20171205/google_cloudbuild1/enum.Result.html), should be
+read by you to obtain the media.
+If such a method also supports a [Response Result](https://docs.rs/google-cloudbuild1/1.0.7+20171205/google_cloudbuild1/trait.ResponseResult.html), it will return that by default.
+You can see it as meta-data for the actual media. To trigger a media download, you will have to set up the builder by making
+this call: `.param("alt", "media")`.
+
+Methods supporting uploads can do so using up to 2 different protocols: 
+*simple* and *resumable*. The distinctiveness of each is represented by customized 
+`doit(...)` methods, which are then named `upload(...)` and `upload_resumable(...)` respectively.
+
+## Customization and Callbacks
+
+You may alter the way an `doit()` method is called by providing a [delegate](https://docs.rs/google-cloudbuild1/1.0.7+20171205/google_cloudbuild1/trait.Delegate.html) to the 
+[Method Builder](https://docs.rs/google-cloudbuild1/1.0.7+20171205/google_cloudbuild1/trait.CallBuilder.html) before making the final `doit()` call. 
+Respective methods will be called to provide progress information, as well as determine whether the system should 
+retry on failure.
+
+The [delegate trait](https://docs.rs/google-cloudbuild1/1.0.7+20171205/google_cloudbuild1/trait.Delegate.html) is default-implemented, allowing you to customize it with minimal effort.
+
+## Optional Parts in Server-Requests
+
+All structures provided by this library are made to be [enocodable](https://docs.rs/google-cloudbuild1/1.0.7+20171205/google_cloudbuild1/trait.RequestValue.html) and 
+[decodable](https://docs.rs/google-cloudbuild1/1.0.7+20171205/google_cloudbuild1/trait.ResponseResult.html) via *json*. Optionals are used to indicate that partial requests are responses 
+are valid.
+Most optionals are are considered [Parts](https://docs.rs/google-cloudbuild1/1.0.7+20171205/google_cloudbuild1/trait.Part.html) which are identifiable by name, which will be sent to 
+the server to indicate either the set parts of the request or the desired parts in the response.
+
+## Builder Arguments
+
+Using [method builders](https://docs.rs/google-cloudbuild1/1.0.7+20171205/google_cloudbuild1/trait.CallBuilder.html), you are able to prepare an action call by repeatedly calling it's methods.
+These will always take a single argument, for which the following statements are true.
+
+* [PODs][wiki-pod] are handed by copy
+* strings are passed as `&str`
+* [request values](https://docs.rs/google-cloudbuild1/1.0.7+20171205/google_cloudbuild1/trait.RequestValue.html) are moved
+
+Arguments will always be copied or cloned into the builder, to make them independent of their original life times.

+The `clouderrorreporting1-beta1` command-line interface *(CLI)* allows to use most features of the *Google Clouderrorreporting* service from the comfort of your terminal.
+
+By default all output is printed to standard out, but flags can be set to direct it into a file independent of your shell's
+capabilities. Errors will be printed to standard error, and cause the program's exit code to be non-zero.
+
+If data-structures are requested, these will be returned as pretty-printed JSON, to be useful as input to other tools.
+
+Everything else about the *Clouderrorreporting* API can be found at the
+[official documentation site](https://cloud.google.com/error-reporting/).
+
+# Installation and Source Code
+
+Install the command-line interface with cargo using:
+
+```bash
+cargo install google-clouderrorreporting1_beta1-cli
+```
+
+Find the source code [on github](https://github.com/Byron/google-apis-rs/tree/master/gen/clouderrorreporting1_beta1-cli).
+
+# Usage
+
+This documentation was generated from the *Clouderrorreporting* API at revision *20171201*. The CLI is at version *1.0.7*.

+Configuration:
+  [--scope <url>]...
+            Specify the authentication a method should be executed in. Each scope
+            requires the user to grant this application permission to use it.
+            If unset, it defaults to the shortest scope url for a particular method.
+  --config-dir <folder>
+            A directory into which we will store our persistent data. Defaults to
+            a user-writable directory that we will create during the first invocation.
+            [default: ~/.google-service-cli]
+  --debug
+            Output all server communication to standard error. `tx` and `rx` are placed
+            into the same stream.
+  --debug-auth
+            Output all communication related to authentication to standard error. `tx`
+            and `rx` are placed into the same stream.
+
+```
+
+# Configuration
+
+The program will store all persistent data in the `~/.google-service-cli` directory in *JSON* files prefixed with `clouderrorreporting1-beta1-`.  You can change the directory used to store configuration with the `--config-dir` flag on a per-invocation basis.
+
+More information about the various kinds of persistent data are given in the following paragraphs.
+
+# Authentication
+
+Most APIs require a user to authenticate any request. If this is the case, the [scope][scopes] determines the 
+set of permissions granted. The granularity of these is usually no more than *read-only* or *full-access*.
+
+If not set, the system will automatically select the smallest feasible scope, e.g. when invoking a
+method that is read-only, it will ask only for a read-only scope. 
+You may use the `--scope` flag to specify a scope directly. 
+All applicable scopes are documented in the respective method's CLI documentation.
+
+The first time a scope is used, the user is asked for permission. Follow the instructions given 
+by the CLI to grant permissions, or to decline.
+
+If a scope was authenticated by the user, the respective information will be stored as *JSON* in the configuration
+directory, e.g. `~/.google-service-cli/clouderrorreporting1-beta1-token-<scope-hash>.json`. No manual management of these tokens
+is necessary.
+
+To revoke granted authentication, please refer to the [official documentation][revoke-access].
+
+# Application Secrets
+
+In order to allow any application to use Google services, it will need to be registered using the 
+[Google Developer Console][google-dev-console]. APIs the application may use are then enabled for it
+one by one. Most APIs can be used for free and have a daily quota.
+
+To allow more comfortable usage of the CLI without forcing anyone to register an own application, the CLI
+comes with a default application secret that is configured accordingly. This also means that heavy usage
+all around the world may deplete the daily quota.
+
+You can workaround this limitation by putting your own secrets file at this location: 
+`~/.google-service-cli/clouderrorreporting1-beta1-secret.json`, assuming that the required *clouderrorreporting* API 
+was enabled for it. Such a secret file can be downloaded in the *Google Developer Console* at 
+*APIs & auth -> Credentials -> Download JSON* and used as is.
+
+Learn more about how to setup Google projects and enable APIs using the [official documentation][google-project-new].
+
+
+# Debugging
+
+Even though the CLI does its best to provide usable error messages, sometimes it might be desirable to know
+what exactly led to a particular issue. This is done by allowing all client-server communication to be 
+output to standard error *as-is*.
+
+The `--debug` flag will print all client-server communication to standard error, whereas the `--debug-auth` flag
+will cause all communication related to authentication to standard error.
+If the `--debug` flag is set, error-results will be debug-printed, possibly yielding more information about the 
+issue at hand.
+
+You may consider redirecting standard error into a file for ease of use, e.g. `clouderrorreporting1-beta1 --debug <resource> <method> [options] 2>debug.txt`.

+The `google-clouderrorreporting1_beta1` library allows access to all features of the *Google Clouderrorreporting* service.
+
+This documentation was generated from *Clouderrorreporting* crate version *1.0.7+20171201*, where *20171201* is the exact revision of the *clouderrorreporting:v1beta1* schema built by the [mako](http://www.makotemplates.org/) code generator *v1.0.7*.
+
+Everything else about the *Clouderrorreporting* *v1_beta1* API can be found at the
+[official documentation site](https://cloud.google.com/error-reporting/).
+# Features
+
+Handle the following *Resources* with ease from the central [hub](https://docs.rs/google-clouderrorreporting1_beta1/1.0.7+20171201/google_clouderrorreporting1_beta1/struct.Clouderrorreporting.html) ... 
+
+* projects
+ * [*delete events*](https://docs.rs/google-clouderrorreporting1_beta1/1.0.7+20171201/google_clouderrorreporting1_beta1/struct.ProjectDeleteEventCall.html), [*events list*](https://docs.rs/google-clouderrorreporting1_beta1/1.0.7+20171201/google_clouderrorreporting1_beta1/struct.ProjectEventListCall.html), [*events report*](https://docs.rs/google-clouderrorreporting1_beta1/1.0.7+20171201/google_clouderrorreporting1_beta1/struct.ProjectEventReportCall.html), [*group stats list*](https://docs.rs/google-clouderrorreporting1_beta1/1.0.7+20171201/google_clouderrorreporting1_beta1/struct.ProjectGroupStatListCall.html), [*groups get*](https://docs.rs/google-clouderrorreporting1_beta1/1.0.7+20171201/google_clouderrorreporting1_beta1/struct.ProjectGroupGetCall.html) and [*groups update*](https://docs.rs/google-clouderrorreporting1_beta1/1.0.7+20171201/google_clouderrorreporting1_beta1/struct.ProjectGroupUpdateCall.html)
+
+
+
+
+# Structure of this Library
+
+The API is structured into the following primary items:
+
+* **[Hub](https://docs.rs/google-clouderrorreporting1_beta1/1.0.7+20171201/google_clouderrorreporting1_beta1/struct.Clouderrorreporting.html)**
+    * a central object to maintain state and allow accessing all *Activities*
+    * creates [*Method Builders*](https://docs.rs/google-clouderrorreporting1_beta1/1.0.7+20171201/google_clouderrorreporting1_beta1/trait.MethodsBuilder.html) which in turn
+      allow access to individual [*Call Builders*](https://docs.rs/google-clouderrorreporting1_beta1/1.0.7+20171201/google_clouderrorreporting1_beta1/trait.CallBuilder.html)
+* **[Resources](https://docs.rs/google-clouderrorreporting1_beta1/1.0.7+20171201/google_clouderrorreporting1_beta1/trait.Resource.html)**
+    * primary types that you can apply *Activities* to
+    * a collection of properties and *Parts*
+    * **[Parts](https://docs.rs/google-clouderrorreporting1_beta1/1.0.7+20171201/google_clouderrorreporting1_beta1/trait.Part.html)**
+        * a collection of properties
+        * never directly used in *Activities*
+* **[Activities](https://docs.rs/google-clouderrorreporting1_beta1/1.0.7+20171201/google_clouderrorreporting1_beta1/trait.CallBuilder.html)**
+    * operations to apply to *Resources*
+
+All *structures* are marked with applicable traits to further categorize them and ease browsing.
+
+Generally speaking, you can invoke *Activities* like this:
+
+```Rust,ignore
+let r = hub.resource().activity(...).doit()
+```
+
+Or specifically ...
+
+```ignore
+let r = hub.projects().groups_get(...).doit()
+let r = hub.projects().groups_update(...).doit()
+```
+
+The `resource()` and `activity(...)` calls create [builders][builder-pattern]. The second one dealing with `Activities` 
+supports various methods to configure the impending operation (not shown here). It is made such that all required arguments have to be 
+specified right away (i.e. `(...)`), whereas all optional ones can be [build up][builder-pattern] as desired.
+The `doit()` method performs the actual communication with the server and returns the respective result.
+
+# Usage
+
+## Setting up your Project
+
+To use this library, you would put the following lines into your `Cargo.toml` file:
+
+```toml
+[dependencies]
+google-clouderrorreporting1_beta1 = "*"
+```
+
+## A complete example
+
+```Rust
+extern crate hyper;
+extern crate hyper_rustls;
+extern crate yup_oauth2 as oauth2;
+extern crate google_clouderrorreporting1_beta1 as clouderrorreporting1_beta1;
+use clouderrorreporting1_beta1::ErrorGroup;
+use clouderrorreporting1_beta1::{Result, Error};
+use std::default::Default;
+use oauth2::{Authenticator, DefaultAuthenticatorDelegate, ApplicationSecret, MemoryStorage};
+use clouderrorreporting1_beta1::Clouderrorreporting;
+
+// Get an ApplicationSecret instance by some means. It contains the `client_id` and 
+// `client_secret`, among other things.
+let secret: ApplicationSecret = Default::default();
+// Instantiate the authenticator. It will choose a suitable authentication flow for you, 
+// unless you replace  `None` with the desired Flow.
+// Provide your own `AuthenticatorDelegate` to adjust the way it operates and get feedback about 
+// what's going on. You probably want to bring in your own `TokenStorage` to persist tokens and
+// retrieve them from storage.
+let auth = Authenticator::new(&secret, DefaultAuthenticatorDelegate,
+                              hyper::Client::with_connector(hyper::net::HttpsConnector::new(hyper_rustls::TlsClient::new())),
+                              <MemoryStorage as Default>::default(), None);
+let mut hub = Clouderrorreporting::new(hyper::Client::with_connector(hyper::net::HttpsConnector::new(hyper_rustls::TlsClient::new())), auth);
+// As the method needs a request, you would usually fill it with the desired information
+// into the respective structure. Some of the parts shown here might not be applicable !
+// Values shown here are possibly random and not representative !
+let mut req = ErrorGroup::default();
+
+// You can configure optional parameters by calling the respective setters at will, and
+// execute the final call using `doit()`.
+// Values shown here are possibly random and not representative !
+let result = hub.projects().groups_update(req, "name")
+             .doit();
+
+match result {
+    Err(e) => match e {
+        // The Error enum provides details about what exactly happened.
+        // You can also just use its `Debug`, `Display` or `Error` traits
+         Error::HttpError(_)
+        |Error::MissingAPIKey
+        |Error::MissingToken(_)
+        |Error::Cancelled
+        |Error::UploadSizeLimitExceeded(_, _)
+        |Error::Failure(_)
+        |Error::BadRequest(_)
+        |Error::FieldClash(_)
+        |Error::JsonDecodeError(_, _) => println!("{}", e),
+    },
+    Ok(res) => println!("Success: {:?}", res),
+}
+
+```
+## Handling Errors
+
+All errors produced by the system are provided either as [Result](https://docs.rs/google-clouderrorreporting1_beta1/1.0.7+20171201/google_clouderrorreporting1_beta1/enum.Result.html) enumeration as return value of 
+the doit() methods, or handed as possibly intermediate results to either the 
+[Hub Delegate](https://docs.rs/google-clouderrorreporting1_beta1/1.0.7+20171201/google_clouderrorreporting1_beta1/trait.Delegate.html), or the [Authenticator Delegate](https://docs.rs/yup-oauth2/*/yup_oauth2/trait.AuthenticatorDelegate.html).
+
+When delegates handle errors or intermediate values, they may have a chance to instruct the system to retry. This 
+makes the system potentially resilient to all kinds of errors.
+
+## Uploads and Downloads
+If a method supports downloads, the response body, which is part of the [Result](https://docs.rs/google-clouderrorreporting1_beta1/1.0.7+20171201/google_clouderrorreporting1_beta1/enum.Result.html), should be
+read by you to obtain the media.
+If such a method also supports a [Response Result](https://docs.rs/google-clouderrorreporting1_beta1/1.0.7+20171201/google_clouderrorreporting1_beta1/trait.ResponseResult.html), it will return that by default.
+You can see it as meta-data for the actual media. To trigger a media download, you will have to set up the builder by making
+this call: `.param("alt", "media")`.
+
+Methods supporting uploads can do so using up to 2 different protocols: 
+*simple* and *resumable*. The distinctiveness of each is represented by customized 
+`doit(...)` methods, which are then named `upload(...)` and `upload_resumable(...)` respectively.
+
+## Customization and Callbacks
+
+You may alter the way an `doit()` method is called by providing a [delegate](https://docs.rs/google-clouderrorreporting1_beta1/1.0.7+20171201/google_clouderrorreporting1_beta1/trait.Delegate.html) to the 
+[Method Builder](https://docs.rs/google-clouderrorreporting1_beta1/1.0.7+20171201/google_clouderrorreporting1_beta1/trait.CallBuilder.html) before making the final `doit()` call. 
+Respective methods will be called to provide progress information, as well as determine whether the system should 
+retry on failure.
+
+The [delegate trait](https://docs.rs/google-clouderrorreporting1_beta1/1.0.7+20171201/google_clouderrorreporting1_beta1/trait.Delegate.html) is default-implemented, allowing you to customize it with minimal effort.
+
+## Optional Parts in Server-Requests
+
+All structures provided by this library are made to be [enocodable](https://docs.rs/google-clouderrorreporting1_beta1/1.0.7+20171201/google_clouderrorreporting1_beta1/trait.RequestValue.html) and 
+[decodable](https://docs.rs/google-clouderrorreporting1_beta1/1.0.7+20171201/google_clouderrorreporting1_beta1/trait.ResponseResult.html) via *json*. Optionals are used to indicate that partial requests are responses 
+are valid.
+Most optionals are are considered [Parts](https://docs.rs/google-clouderrorreporting1_beta1/1.0.7+20171201/google_clouderrorreporting1_beta1/trait.Part.html) which are identifiable by name, which will be sent to 
+the server to indicate either the set parts of the request or the desired parts in the response.
+
+## Builder Arguments
+
+Using [method builders](https://docs.rs/google-clouderrorreporting1_beta1/1.0.7+20171201/google_clouderrorreporting1_beta1/trait.CallBuilder.html), you are able to prepare an action call by repeatedly calling it's methods.
+These will always take a single argument, for which the following statements are true.
+
+* [PODs][wiki-pod] are handed by copy
+* strings are passed as `&str`
+* [request values](https://docs.rs/google-clouderrorreporting1_beta1/1.0.7+20171201/google_clouderrorreporting1_beta1/trait.RequestValue.html) are moved
+
+Arguments will always be copied or cloned into the builder, to make them independent of their original life times.

+The `cloudtrace1` command-line interface *(CLI)* allows to use most features of the *Google Cloud Trace* service from the comfort of your terminal.
+
+By default all output is printed to standard out, but flags can be set to direct it into a file independent of your shell's
+capabilities. Errors will be printed to standard error, and cause the program's exit code to be non-zero.
+
+If data-structures are requested, these will be returned as pretty-printed JSON, to be useful as input to other tools.
+
+Everything else about the *Cloud Trace* API can be found at the
+[official documentation site](https://cloud.google.com/trace).
+
+# Installation and Source Code
+
+Install the command-line interface with cargo using:
+
+```bash
+cargo install google-cloudtrace1-cli
+```
+
+Find the source code [on github](https://github.com/Byron/google-apis-rs/tree/master/gen/cloudtrace1-cli).
+
+# Usage
+
+This documentation was generated from the *Cloud Trace* API at revision *20171202*. The CLI is at version *1.0.7*.
+
+```bash
+cloudtrace1 [options]
+        projects
+                patch-traces <project-id> (-r <kv>)... [-p <v>]... [-o <out>]
+                traces-get <project-id> <trace-id> [-p <v>]... [-o <out>]
+                traces-list <project-id> [-p <v>]... [-o <out>]
+  cloudtrace1 --help
+
+Configuration:
+  [--scope <url>]...
+            Specify the authentication a method should be executed in. Each scope
+            requires the user to grant this application permission to use it.
+            If unset, it defaults to the shortest scope url for a particular method.
+  --config-dir <folder>
+            A directory into which we will store our persistent data. Defaults to
+            a user-writable directory that we will create during the first invocation.
+            [default: ~/.google-service-cli]
+  --debug
+            Output all server communication to standard error. `tx` and `rx` are placed
+            into the same stream.
+  --debug-auth
+            Output all communication related to authentication to standard error. `tx`
+            and `rx` are placed into the same stream.
+
+```
+
+# Configuration
+
+The program will store all persistent data in the `~/.google-service-cli` directory in *JSON* files prefixed with `cloudtrace1-`.  You can change the directory used to store configuration with the `--config-dir` flag on a per-invocation basis.
+
+More information about the various kinds of persistent data are given in the following paragraphs.
+
+# Authentication
+
+Most APIs require a user to authenticate any request. If this is the case, the [scope][scopes] determines the 
+set of permissions granted. The granularity of these is usually no more than *read-only* or *full-access*.
+
+If not set, the system will automatically select the smallest feasible scope, e.g. when invoking a
+method that is read-only, it will ask only for a read-only scope. 
+You may use the `--scope` flag to specify a scope directly. 
+All applicable scopes are documented in the respective method's CLI documentation.
+
+The first time a scope is used, the user is asked for permission. Follow the instructions given 
+by the CLI to grant permissions, or to decline.
+
+If a scope was authenticated by the user, the respective information will be stored as *JSON* in the configuration
+directory, e.g. `~/.google-service-cli/cloudtrace1-token-<scope-hash>.json`. No manual management of these tokens
+is necessary.
+
+To revoke granted authentication, please refer to the [official documentation][revoke-access].
+
+# Application Secrets
+
+In order to allow any application to use Google services, it will need to be registered using the 
+[Google Developer Console][google-dev-console]. APIs the application may use are then enabled for it
+one by one. Most APIs can be used for free and have a daily quota.
+
+To allow more comfortable usage of the CLI without forcing anyone to register an own application, the CLI
+comes with a default application secret that is configured accordingly. This also means that heavy usage
+all around the world may deplete the daily quota.
+
+You can workaround this limitation by putting your own secrets file at this location: 
+`~/.google-service-cli/cloudtrace1-secret.json`, assuming that the required *cloudtrace* API 
+was enabled for it. Such a secret file can be downloaded in the *Google Developer Console* at 
+*APIs & auth -> Credentials -> Download JSON* and used as is.
+
+Learn more about how to setup Google projects and enable APIs using the [official documentation][google-project-new].
+
+
+# Debugging
+
+Even though the CLI does its best to provide usable error messages, sometimes it might be desirable to know
+what exactly led to a particular issue. This is done by allowing all client-server communication to be 
+output to standard error *as-is*.
+
+The `--debug` flag will print all client-server communication to standard error, whereas the `--debug-auth` flag
+will cause all communication related to authentication to standard error.
+If the `--debug` flag is set, error-results will be debug-printed, possibly yielding more information about the 
+issue at hand.
+
+You may consider redirecting standard error into a file for ease of use, e.g. `cloudtrace1 --debug <resource> <method> [options] 2>debug.txt`.

+# Structure of this Library
+
+The API is structured into the following primary items:
+
+* **[Hub](https://docs.rs/google-cloudtrace1/1.0.7+20171202/google_cloudtrace1/struct.CloudTrace.html)**
+    * a central object to maintain state and allow accessing all *Activities*
+    * creates [*Method Builders*](https://docs.rs/google-cloudtrace1/1.0.7+20171202/google_cloudtrace1/trait.MethodsBuilder.html) which in turn
+      allow access to individual [*Call Builders*](https://docs.rs/google-cloudtrace1/1.0.7+20171202/google_cloudtrace1/trait.CallBuilder.html)
+* **[Resources](https://docs.rs/google-cloudtrace1/1.0.7+20171202/google_cloudtrace1/trait.Resource.html)**
+    * primary types that you can apply *Activities* to
+    * a collection of properties and *Parts*
+    * **[Parts](https://docs.rs/google-cloudtrace1/1.0.7+20171202/google_cloudtrace1/trait.Part.html)**
+        * a collection of properties
+        * never directly used in *Activities*
+* **[Activities](https://docs.rs/google-cloudtrace1/1.0.7+20171202/google_cloudtrace1/trait.CallBuilder.html)**
+    * operations to apply to *Resources*
+
+All *structures* are marked with applicable traits to further categorize them and ease browsing.
+
+Generally speaking, you can invoke *Activities* like this:
+
+```Rust,ignore
+let r = hub.resource().activity(...).doit()
+```
+
+Or specifically ...
+
+```ignore
+let r = hub.projects().traces_get(...).doit()
+```
+
+The `resource()` and `activity(...)` calls create [builders][builder-pattern]. The second one dealing with `Activities` 
+supports various methods to configure the impending operation (not shown here). It is made such that all required arguments have to be 
+specified right away (i.e. `(...)`), whereas all optional ones can be [build up][builder-pattern] as desired.
+The `doit()` method performs the actual communication with the server and returns the respective result.
+
+# Usage
+
+## Setting up your Project
+
+To use this library, you would put the following lines into your `Cargo.toml` file:
+
+```toml
+[dependencies]
+google-cloudtrace1 = "*"
+```
+
+## A complete example
+
+```Rust
+extern crate hyper;
+extern crate hyper_rustls;
+extern crate yup_oauth2 as oauth2;
+extern crate google_cloudtrace1 as cloudtrace1;
+use cloudtrace1::{Result, Error};
+use std::default::Default;
+use oauth2::{Authenticator, DefaultAuthenticatorDelegate, ApplicationSecret, MemoryStorage};
+use cloudtrace1::CloudTrace;
+
+// Get an ApplicationSecret instance by some means. It contains the `client_id` and 
+// `client_secret`, among other things.
+let secret: ApplicationSecret = Default::default();
+// Instantiate the authenticator. It will choose a suitable authentication flow for you, 
+// unless you replace  `None` with the desired Flow.
+// Provide your own `AuthenticatorDelegate` to adjust the way it operates and get feedback about 
+// what's going on. You probably want to bring in your own `TokenStorage` to persist tokens and
+// retrieve them from storage.
+let auth = Authenticator::new(&secret, DefaultAuthenticatorDelegate,
+                              hyper::Client::with_connector(hyper::net::HttpsConnector::new(hyper_rustls::TlsClient::new())),
+                              <MemoryStorage as Default>::default(), None);
+let mut hub = CloudTrace::new(hyper::Client::with_connector(hyper::net::HttpsConnector::new(hyper_rustls::TlsClient::new())), auth);
+// You can configure optional parameters by calling the respective setters at will, and
+// execute the final call using `doit()`.
+// Values shown here are possibly random and not representative !
+let result = hub.projects().traces_get("projectId", "traceId")
+             .doit();
+
+match result {
+    Err(e) => match e {
+        // The Error enum provides details about what exactly happened.
+        // You can also just use its `Debug`, `Display` or `Error` traits
+         Error::HttpError(_)
+        |Error::MissingAPIKey
+        |Error::MissingToken(_)
+        |Error::Cancelled
+        |Error::UploadSizeLimitExceeded(_, _)
+        |Error::Failure(_)
+        |Error::BadRequest(_)
+        |Error::FieldClash(_)
+        |Error::JsonDecodeError(_, _) => println!("{}", e),
+    },
+    Ok(res) => println!("Success: {:?}", res),
+}
+
+```
+## Handling Errors
+
+All errors produced by the system are provided either as [Result](https://docs.rs/google-cloudtrace1/1.0.7+20171202/google_cloudtrace1/enum.Result.html) enumeration as return value of 
+the doit() methods, or handed as possibly intermediate results to either the 
+[Hub Delegate](https://docs.rs/google-cloudtrace1/1.0.7+20171202/google_cloudtrace1/trait.Delegate.html), or the [Authenticator Delegate](https://docs.rs/yup-oauth2/*/yup_oauth2/trait.AuthenticatorDelegate.html).
+
+When delegates handle errors or intermediate values, they may have a chance to instruct the system to retry. This 
+makes the system potentially resilient to all kinds of errors.
+
+## Uploads and Downloads
+If a method supports downloads, the response body, which is part of the [Result](https://docs.rs/google-cloudtrace1/1.0.7+20171202/google_cloudtrace1/enum.Result.html), should be
+read by you to obtain the media.
+If such a method also supports a [Response Result](https://docs.rs/google-cloudtrace1/1.0.7+20171202/google_cloudtrace1/trait.ResponseResult.html), it will return that by default.
+You can see it as meta-data for the actual media. To trigger a media download, you will have to set up the builder by making
+this call: `.param("alt", "media")`.
+
+Methods supporting uploads can do so using up to 2 different protocols: 
+*simple* and *resumable*. The distinctiveness of each is represented by customized 
+`doit(...)` methods, which are then named `upload(...)` and `upload_resumable(...)` respectively.
+
+## Customization and Callbacks
+
+You may alter the way an `doit()` method is called by providing a [delegate](https://docs.rs/google-cloudtrace1/1.0.7+20171202/google_cloudtrace1/trait.Delegate.html) to the 
+[Method Builder](https://docs.rs/google-cloudtrace1/1.0.7+20171202/google_cloudtrace1/trait.CallBuilder.html) before making the final `doit()` call. 
+Respective methods will be called to provide progress information, as well as determine whether the system should 
+retry on failure.
+
+The [delegate trait](https://docs.rs/google-cloudtrace1/1.0.7+20171202/google_cloudtrace1/trait.Delegate.html) is default-implemented, allowing you to customize it with minimal effort.
+
+## Optional Parts in Server-Requests
+
+All structures provided by this library are made to be [enocodable](https://docs.rs/google-cloudtrace1/1.0.7+20171202/google_cloudtrace1/trait.RequestValue.html) and 
+[decodable](https://docs.rs/google-cloudtrace1/1.0.7+20171202/google_cloudtrace1/trait.ResponseResult.html) via *json*. Optionals are used to indicate that partial requests are responses 
+are valid.
+Most optionals are are considered [Parts](https://docs.rs/google-cloudtrace1/1.0.7+20171202/google_cloudtrace1/trait.Part.html) which are identifiable by name, which will be sent to 
+the server to indicate either the set parts of the request or the desired parts in the response.
+
+## Builder Arguments
+
+Using [method builders](https://docs.rs/google-cloudtrace1/1.0.7+20171202/google_cloudtrace1/trait.CallBuilder.html), you are able to prepare an action call by repeatedly calling it's methods.
+These will always take a single argument, for which the following statements are true.
+
+* [PODs][wiki-pod] are handed by copy
+* strings are passed as `&str`
+* [request values](https://docs.rs/google-cloudtrace1/1.0.7+20171202/google_cloudtrace1/trait.RequestValue.html) are moved
+
+Arguments will always be copied or cloned into the builder, to make them independent of their original life times.

+The `cloudtrace2` command-line interface *(CLI)* allows to use most features of the *Google Cloud Trace* service from the comfort of your terminal.
+
+By default all output is printed to standard out, but flags can be set to direct it into a file independent of your shell's
+capabilities. Errors will be printed to standard error, and cause the program's exit code to be non-zero.
+
+If data-structures are requested, these will be returned as pretty-printed JSON, to be useful as input to other tools.
+
+Everything else about the *Cloud Trace* API can be found at the
+[official documentation site](https://cloud.google.com/trace).
+
+# Installation and Source Code
+
+Install the command-line interface with cargo using:
+
+```bash
+cargo install google-cloudtrace2-cli
+```
+
+Find the source code [on github](https://github.com/Byron/google-apis-rs/tree/master/gen/cloudtrace2-cli).
+
+# Usage
+
+This documentation was generated from the *Cloud Trace* API at revision *20171202*. The CLI is at version *1.0.7*.
+
+```bash
+cloudtrace2 [options]
+        projects
+                traces-batch-write <name> (-r <kv>)... [-p <v>]... [-o <out>]
+                traces-spans-create <name> (-r <kv>)... [-p <v>]... [-o <out>]
+  cloudtrace2 --help
+
+Configuration:
+  [--scope <url>]...
+            Specify the authentication a method should be executed in. Each scope
+            requires the user to grant this application permission to use it.
+            If unset, it defaults to the shortest scope url for a particular method.
+  --config-dir <folder>
+            A directory into which we will store our persistent data. Defaults to
+            a user-writable directory that we will create during the first invocation.
+            [default: ~/.google-service-cli]
+  --debug
+            Output all server communication to standard error. `tx` and `rx` are placed
+            into the same stream.
+  --debug-auth
+            Output all communication related to authentication to standard error. `tx`
+            and `rx` are placed into the same stream.
+
+```
+
+# Configuration
+
+The program will store all persistent data in the `~/.google-service-cli` directory in *JSON* files prefixed with `cloudtrace2-`.  You can change the directory used to store configuration with the `--config-dir` flag on a per-invocation basis.
+
+More information about the various kinds of persistent data are given in the following paragraphs.
+
+# Authentication
+
+Most APIs require a user to authenticate any request. If this is the case, the [scope][scopes] determines the 
+set of permissions granted. The granularity of these is usually no more than *read-only* or *full-access*.
+
+If not set, the system will automatically select the smallest feasible scope, e.g. when invoking a
+method that is read-only, it will ask only for a read-only scope. 
+You may use the `--scope` flag to specify a scope directly. 
+All applicable scopes are documented in the respective method's CLI documentation.
+
+The first time a scope is used, the user is asked for permission. Follow the instructions given 
+by the CLI to grant permissions, or to decline.
+
+If a scope was authenticated by the user, the respective information will be stored as *JSON* in the configuration
+directory, e.g. `~/.google-service-cli/cloudtrace2-token-<scope-hash>.json`. No manual management of these tokens
+is necessary.
+
+To revoke granted authentication, please refer to the [official documentation][revoke-access].
+
+# Application Secrets
+
+In order to allow any application to use Google services, it will need to be registered using the 
+[Google Developer Console][google-dev-console]. APIs the application may use are then enabled for it
+one by one. Most APIs can be used for free and have a daily quota.
+
+To allow more comfortable usage of the CLI without forcing anyone to register an own application, the CLI
+comes with a default application secret that is configured accordingly. This also means that heavy usage
+all around the world may deplete the daily quota.
+
+You can workaround this limitation by putting your own secrets file at this location: 
+`~/.google-service-cli/cloudtrace2-secret.json`, assuming that the required *cloudtrace* API 
+was enabled for it. Such a secret file can be downloaded in the *Google Developer Console* at 
+*APIs & auth -> Credentials -> Download JSON* and used as is.
+
+Learn more about how to setup Google projects and enable APIs using the [official documentation][google-project-new].
+
+
+# Debugging
+
+Even though the CLI does its best to provide usable error messages, sometimes it might be desirable to know
+what exactly led to a particular issue. This is done by allowing all client-server communication to be 
+output to standard error *as-is*.
+
+The `--debug` flag will print all client-server communication to standard error, whereas the `--debug-auth` flag
+will cause all communication related to authentication to standard error.
+If the `--debug` flag is set, error-results will be debug-printed, possibly yielding more information about the 
+issue at hand.
+
+You may consider redirecting standard error into a file for ease of use, e.g. `cloudtrace2 --debug <resource> <method> [options] 2>debug.txt`.

+The `google-cloudtrace2` library allows access to all features of the *Google Cloud Trace* service.
+
+This documentation was generated from *Cloud Trace* crate version *1.0.7+20171202*, where *20171202* is the exact revision of the *cloudtrace:v2* schema built by the [mako](http://www.makotemplates.org/) code generator *v1.0.7*.
+
+Everything else about the *Cloud Trace* *v2* API can be found at the
+[official documentation site](https://cloud.google.com/trace).
+# Features
+
+Handle the following *Resources* with ease from the central [hub](https://docs.rs/google-cloudtrace2/1.0.7+20171202/google_cloudtrace2/struct.CloudTrace.html) ... 
+
+* projects
+ * [*traces batch write*](https://docs.rs/google-cloudtrace2/1.0.7+20171202/google_cloudtrace2/struct.ProjectTraceBatchWriteCall.html) and [*traces spans create*](https://docs.rs/google-cloudtrace2/1.0.7+20171202/google_cloudtrace2/struct.ProjectTraceSpanCreateCall.html)
+
+
+
+
+# Structure of this Library
+
+The API is structured into the following primary items:
+
+* **[Hub](https://docs.rs/google-cloudtrace2/1.0.7+20171202/google_cloudtrace2/struct.CloudTrace.html)**
+    * a central object to maintain state and allow accessing all *Activities*
+    * creates [*Method Builders*](https://docs.rs/google-cloudtrace2/1.0.7+20171202/google_cloudtrace2/trait.MethodsBuilder.html) which in turn
+      allow access to individual [*Call Builders*](https://docs.rs/google-cloudtrace2/1.0.7+20171202/google_cloudtrace2/trait.CallBuilder.html)
+* **[Resources](https://docs.rs/google-cloudtrace2/1.0.7+20171202/google_cloudtrace2/trait.Resource.html)**
+    * primary types that you can apply *Activities* to
+    * a collection of properties and *Parts*
+    * **[Parts](https://docs.rs/google-cloudtrace2/1.0.7+20171202/google_cloudtrace2/trait.Part.html)**
+        * a collection of properties
+        * never directly used in *Activities*
+* **[Activities](https://docs.rs/google-cloudtrace2/1.0.7+20171202/google_cloudtrace2/trait.CallBuilder.html)**
+    * operations to apply to *Resources*
+
+All *structures* are marked with applicable traits to further categorize them and ease browsing.
+
+Generally speaking, you can invoke *Activities* like this:
+
+```Rust,ignore
+let r = hub.resource().activity(...).doit()
+```
+
+Or specifically ...
+
+```ignore
+let r = hub.projects().traces_spans_create(...).doit()
+```
+
+The `resource()` and `activity(...)` calls create [builders][builder-pattern]. The second one dealing with `Activities` 
+supports various methods to configure the impending operation (not shown here). It is made such that all required arguments have to be 
+specified right away (i.e. `(...)`), whereas all optional ones can be [build up][builder-pattern] as desired.
+The `doit()` method performs the actual communication with the server and returns the respective result.
+
+# Usage
+
+## Setting up your Project
+
+To use this library, you would put the following lines into your `Cargo.toml` file:
+
+```toml
+[dependencies]
+google-cloudtrace2 = "*"
+```
+
+## A complete example
+
+```Rust
+extern crate hyper;
+extern crate hyper_rustls;
+extern crate yup_oauth2 as oauth2;
+extern crate google_cloudtrace2 as cloudtrace2;
+use cloudtrace2::Span;
+use cloudtrace2::{Result, Error};
+use std::default::Default;
+use oauth2::{Authenticator, DefaultAuthenticatorDelegate, ApplicationSecret, MemoryStorage};
+use cloudtrace2::CloudTrace;
+
+// Get an ApplicationSecret instance by some means. It contains the `client_id` and 
+// `client_secret`, among other things.
+let secret: ApplicationSecret = Default::default();
+// Instantiate the authenticator. It will choose a suitable authentication flow for you, 
+// unless you replace  `None` with the desired Flow.
+// Provide your own `AuthenticatorDelegate` to adjust the way it operates and get feedback about 
+// what's going on. You probably want to bring in your own `TokenStorage` to persist tokens and
+// retrieve them from storage.
+let auth = Authenticator::new(&secret, DefaultAuthenticatorDelegate,
+                              hyper::Client::with_connector(hyper::net::HttpsConnector::new(hyper_rustls::TlsClient::new())),
+                              <MemoryStorage as Default>::default(), None);
+let mut hub = CloudTrace::new(hyper::Client::with_connector(hyper::net::HttpsConnector::new(hyper_rustls::TlsClient::new())), auth);
+// As the method needs a request, you would usually fill it with the desired information
+// into the respective structure. Some of the parts shown here might not be applicable !
+// Values shown here are possibly random and not representative !
+let mut req = Span::default();
+
+// You can configure optional parameters by calling the respective setters at will, and
+// execute the final call using `doit()`.
+// Values shown here are possibly random and not representative !
+let result = hub.projects().traces_spans_create(req, "name")
+             .doit();
+
+match result {
+    Err(e) => match e {
+        // The Error enum provides details about what exactly happened.
+        // You can also just use its `Debug`, `Display` or `Error` traits
+         Error::HttpError(_)
+        |Error::MissingAPIKey
+        |Error::MissingToken(_)
+        |Error::Cancelled
+        |Error::UploadSizeLimitExceeded(_, _)
+        |Error::Failure(_)
+        |Error::BadRequest(_)
+        |Error::FieldClash(_)
+        |Error::JsonDecodeError(_, _) => println!("{}", e),
+    },
+    Ok(res) => println!("Success: {:?}", res),
+}
+
+```
+## Handling Errors
+
+All errors produced by the system are provided either as [Result](https://docs.rs/google-cloudtrace2/1.0.7+20171202/google_cloudtrace2/enum.Result.html) enumeration as return value of 
+the doit() methods, or handed as possibly intermediate results to either the 
+[Hub Delegate](https://docs.rs/google-cloudtrace2/1.0.7+20171202/google_cloudtrace2/trait.Delegate.html), or the [Authenticator Delegate](https://docs.rs/yup-oauth2/*/yup_oauth2/trait.AuthenticatorDelegate.html).
+
+When delegates handle errors or intermediate values, they may have a chance to instruct the system to retry. This 
+makes the system potentially resilient to all kinds of errors.
+
+## Uploads and Downloads
+If a method supports downloads, the response body, which is part of the [Result](https://docs.rs/google-cloudtrace2/1.0.7+20171202/google_cloudtrace2/enum.Result.html), should be
+read by you to obtain the media.
+If such a method also supports a [Response Result](https://docs.rs/google-cloudtrace2/1.0.7+20171202/google_cloudtrace2/trait.ResponseResult.html), it will return that by default.
+You can see it as meta-data for the actual media. To trigger a media download, you will have to set up the builder by making
+this call: `.param("alt", "media")`.
+
+Methods supporting uploads can do so using up to 2 different protocols: 
+*simple* and *resumable*. The distinctiveness of each is represented by customized 
+`doit(...)` methods, which are then named `upload(...)` and `upload_resumable(...)` respectively.
+
+## Customization and Callbacks
+
+You may alter the way an `doit()` method is called by providing a [delegate](https://docs.rs/google-cloudtrace2/1.0.7+20171202/google_cloudtrace2/trait.Delegate.html) to the 
+[Method Builder](https://docs.rs/google-cloudtrace2/1.0.7+20171202/google_cloudtrace2/trait.CallBuilder.html) before making the final `doit()` call. 
+Respective methods will be called to provide progress information, as well as determine whether the system should 
+retry on failure.
+
+The [delegate trait](https://docs.rs/google-cloudtrace2/1.0.7+20171202/google_cloudtrace2/trait.Delegate.html) is default-implemented, allowing you to customize it with minimal effort.
+
+## Optional Parts in Server-Requests
+
+All structures provided by this library are made to be [enocodable](https://docs.rs/google-cloudtrace2/1.0.7+20171202/google_cloudtrace2/trait.RequestValue.html) and 
+[decodable](https://docs.rs/google-cloudtrace2/1.0.7+20171202/google_cloudtrace2/trait.ResponseResult.html) via *json*. Optionals are used to indicate that partial requests are responses 
+are valid.
+Most optionals are are considered [Parts](https://docs.rs/google-cloudtrace2/1.0.7+20171202/google_cloudtrace2/trait.Part.html) which are identifiable by name, which will be sent to 
+the server to indicate either the set parts of the request or the desired parts in the response.
+
+## Builder Arguments
+
+Using [method builders](https://docs.rs/google-cloudtrace2/1.0.7+20171202/google_cloudtrace2/trait.CallBuilder.html), you are able to prepare an action call by repeatedly calling it's methods.
+These will always take a single argument, for which the following statements are true.
+
+* [PODs][wiki-pod] are handed by copy
+* strings are passed as `&str`
+* [request values](https://docs.rs/google-cloudtrace2/1.0.7+20171202/google_cloudtrace2/trait.RequestValue.html) are moved
+
+Arguments will always be copied or cloned into the builder, to make them independent of their original life times.

+The `consumersurveys2` command-line interface *(CLI)* allows to use most features of the *Google Consumer Surveys* service from the comfort of your terminal.
+
+By default all output is printed to standard out, but flags can be set to direct it into a file independent of your shell's
+capabilities. Errors will be printed to standard error, and cause the program's exit code to be non-zero.
+
+If data-structures are requested, these will be returned as pretty-printed JSON, to be useful as input to other tools.
+
+# Installation and Source Code
+
+Install the command-line interface with cargo using:
+
+```bash
+cargo install google-consumersurveys2-cli
+```
+
+Find the source code [on github](https://github.com/Byron/google-apis-rs/tree/master/gen/consumersurveys2-cli).
+
+# Usage
+
+This documentation was generated from the *Consumer Surveys* API at revision *20170407*. The CLI is at version *1.0.7*.
+
+```bash
+consumersurveys2 [options]
+        mobileapppanels
+                get <panel-id> [-p <v>]... [-o <out>]
+                list [-p <v>]... [-o <out>]
+                update <panel-id> (-r <kv>)... [-p <v>]... [-o <out>]
+        results
+                get <survey-url-id> (-r <kv>)... [-p <v>]... [-o <out>]
+        surveys
+                delete <survey-url-id> [-p <v>]... [-o <out>]
+                get <survey-url-id> [-p <v>]... [-o <out>]
+                insert (-r <kv>)... [-p <v>]... [-o <out>]
+                list [-p <v>]... [-o <out>]
+                start <resource-id> (-r <kv>)... [-p <v>]... [-o <out>]
+                stop <resource-id> [-p <v>]... [-o <out>]
+                update <survey-url-id> (-r <kv>)... [-p <v>]... [-o <out>]
+  consumersurveys2 --help
+
+Configuration:
+  [--scope <url>]...
+            Specify the authentication a method should be executed in. Each scope
+            requires the user to grant this application permission to use it.
+            If unset, it defaults to the shortest scope url for a particular method.
+  --config-dir <folder>
+            A directory into which we will store our persistent data. Defaults to
+            a user-writable directory that we will create during the first invocation.
+            [default: ~/.google-service-cli]
+  --debug
+            Output all server communication to standard error. `tx` and `rx` are placed
+            into the same stream.
+  --debug-auth
+            Output all communication related to authentication to standard error. `tx`
+            and `rx` are placed into the same stream.
+
+```
+
+# Configuration
+
+The program will store all persistent data in the `~/.google-service-cli` directory in *JSON* files prefixed with `consumersurveys2-`.  You can change the directory used to store configuration with the `--config-dir` flag on a per-invocation basis.
+
+More information about the various kinds of persistent data are given in the following paragraphs.
+
+# Authentication
+
+Most APIs require a user to authenticate any request. If this is the case, the [scope][scopes] determines the 
+set of permissions granted. The granularity of these is usually no more than *read-only* or *full-access*.
+
+If not set, the system will automatically select the smallest feasible scope, e.g. when invoking a
+method that is read-only, it will ask only for a read-only scope. 
+You may use the `--scope` flag to specify a scope directly. 
+All applicable scopes are documented in the respective method's CLI documentation.
+
+The first time a scope is used, the user is asked for permission. Follow the instructions given 
+by the CLI to grant permissions, or to decline.
+
+If a scope was authenticated by the user, the respective information will be stored as *JSON* in the configuration
+directory, e.g. `~/.google-service-cli/consumersurveys2-token-<scope-hash>.json`. No manual management of these tokens
+is necessary.
+
+To revoke granted authentication, please refer to the [official documentation][revoke-access].
+
+# Application Secrets
+
+In order to allow any application to use Google services, it will need to be registered using the 
+[Google Developer Console][google-dev-console]. APIs the application may use are then enabled for it
+one by one. Most APIs can be used for free and have a daily quota.
+
+To allow more comfortable usage of the CLI without forcing anyone to register an own application, the CLI
+comes with a default application secret that is configured accordingly. This also means that heavy usage
+all around the world may deplete the daily quota.
+
+You can workaround this limitation by putting your own secrets file at this location: 
+`~/.google-service-cli/consumersurveys2-secret.json`, assuming that the required *consumersurveys* API 
+was enabled for it. Such a secret file can be downloaded in the *Google Developer Console* at 
+*APIs & auth -> Credentials -> Download JSON* and used as is.
+
+Learn more about how to setup Google projects and enable APIs using the [official documentation][google-project-new].
+
+
+# Debugging
+
+Even though the CLI does its best to provide usable error messages, sometimes it might be desirable to know
+what exactly led to a particular issue. This is done by allowing all client-server communication to be 
+output to standard error *as-is*.
+
+The `--debug` flag will print all client-server communication to standard error, whereas the `--debug-auth` flag
+will cause all communication related to authentication to standard error.
+If the `--debug` flag is set, error-results will be debug-printed, possibly yielding more information about the 
+issue at hand.
+
+You may consider redirecting standard error into a file for ease of use, e.g. `consumersurveys2 --debug <resource> <method> [options] 2>debug.txt`.

+The `google-consumersurveys2` library allows access to all features of the *Google Consumer Surveys* service.
+
+This documentation was generated from *Consumer Surveys* crate version *1.0.7+20170407*, where *20170407* is the exact revision of the *consumersurveys:v2* schema built by the [mako](http://www.makotemplates.org/) code generator *v1.0.7*.
+# Features

+
+
+# Structure of this Library
+
+The API is structured into the following primary items:
+
+* **[Hub](https://docs.rs/google-consumersurveys2/1.0.7+20170407/google_consumersurveys2/struct.ConsumerSurveys.html)**
+    * a central object to maintain state and allow accessing all *Activities*
+    * creates [*Method Builders*](https://docs.rs/google-consumersurveys2/1.0.7+20170407/google_consumersurveys2/trait.MethodsBuilder.html) which in turn
+      allow access to individual [*Call Builders*](https://docs.rs/google-consumersurveys2/1.0.7+20170407/google_consumersurveys2/trait.CallBuilder.html)
+* **[Resources](https://docs.rs/google-consumersurveys2/1.0.7+20170407/google_consumersurveys2/trait.Resource.html)**
+    * primary types that you can apply *Activities* to
+    * a collection of properties and *Parts*
+    * **[Parts](https://docs.rs/google-consumersurveys2/1.0.7+20170407/google_consumersurveys2/trait.Part.html)**
+        * a collection of properties
+        * never directly used in *Activities*
+* **[Activities](https://docs.rs/google-consumersurveys2/1.0.7+20170407/google_consumersurveys2/trait.CallBuilder.html)**
+    * operations to apply to *Resources*
+
+All *structures* are marked with applicable traits to further categorize them and ease browsing.
+
+Generally speaking, you can invoke *Activities* like this:
+
+```Rust,ignore
+let r = hub.resource().activity(...).doit()
+```
+
+Or specifically ...
+
+```ignore
+let r = hub.surveys().delete(...).doit()
+let r = hub.surveys().insert(...).doit()
+let r = hub.surveys().list(...).doit()
+let r = hub.surveys().update(...).doit()
+let r = hub.surveys().get(...).doit()
+let r = hub.surveys().stop(...).doit()
+let r = hub.surveys().start(...).doit()
+```
+
+The `resource()` and `activity(...)` calls create [builders][builder-pattern]. The second one dealing with `Activities` 
+supports various methods to configure the impending operation (not shown here). It is made such that all required arguments have to be 
+specified right away (i.e. `(...)`), whereas all optional ones can be [build up][builder-pattern] as desired.
+The `doit()` method performs the actual communication with the server and returns the respective result.
+
+# Usage
+
+## Setting up your Project
+
+To use this library, you would put the following lines into your `Cargo.toml` file:
+
+```toml
+[dependencies]
+google-consumersurveys2 = "*"
+```
+
+## A complete example
+
+```Rust
+extern crate hyper;
+extern crate hyper_rustls;
+extern crate yup_oauth2 as oauth2;
+extern crate google_consumersurveys2 as consumersurveys2;
+use consumersurveys2::{Result, Error};
+use std::default::Default;
+use oauth2::{Authenticator, DefaultAuthenticatorDelegate, ApplicationSecret, MemoryStorage};
+use consumersurveys2::ConsumerSurveys;
+
+// Get an ApplicationSecret instance by some means. It contains the `client_id` and 
+// `client_secret`, among other things.
+let secret: ApplicationSecret = Default::default();
+// Instantiate the authenticator. It will choose a suitable authentication flow for you, 
+// unless you replace  `None` with the desired Flow.
+// Provide your own `AuthenticatorDelegate` to adjust the way it operates and get feedback about 
+// what's going on. You probably want to bring in your own `TokenStorage` to persist tokens and
+// retrieve them from storage.
+let auth = Authenticator::new(&secret, DefaultAuthenticatorDelegate,
+                              hyper::Client::with_connector(hyper::net::HttpsConnector::new(hyper_rustls::TlsClient::new())),
+                              <MemoryStorage as Default>::default(), None);
+let mut hub = ConsumerSurveys::new(hyper::Client::with_connector(hyper::net::HttpsConnector::new(hyper_rustls::TlsClient::new())), auth);
+// You can configure optional parameters by calling the respective setters at will, and
+// execute the final call using `doit()`.
+// Values shown here are possibly random and not representative !
+let result = hub.surveys().list()
+             .token("eirmod")
+             .start_index(53)
+             .max_results(36)
+             .doit();
+
+match result {
+    Err(e) => match e {
+        // The Error enum provides details about what exactly happened.
+        // You can also just use its `Debug`, `Display` or `Error` traits
+         Error::HttpError(_)
+        |Error::MissingAPIKey
+        |Error::MissingToken(_)
+        |Error::Cancelled
+        |Error::UploadSizeLimitExceeded(_, _)
+        |Error::Failure(_)
+        |Error::BadRequest(_)
+        |Error::FieldClash(_)
+        |Error::JsonDecodeError(_, _) => println!("{}", e),
+    },
+    Ok(res) => println!("Success: {:?}", res),
+}
+
+```
+## Handling Errors
+
+All errors produced by the system are provided either as [Result](https://docs.rs/google-consumersurveys2/1.0.7+20170407/google_consumersurveys2/enum.Result.html) enumeration as return value of 
+the doit() methods, or handed as possibly intermediate results to either the 
+[Hub Delegate](https://docs.rs/google-consumersurveys2/1.0.7+20170407/google_consumersurveys2/trait.Delegate.html), or the [Authenticator Delegate](https://docs.rs/yup-oauth2/*/yup_oauth2/trait.AuthenticatorDelegate.html).
+
+When delegates handle errors or intermediate values, they may have a chance to instruct the system to retry. This 
+makes the system potentially resilient to all kinds of errors.
+
+## Uploads and Downloads
+If a method supports downloads, the response body, which is part of the [Result](https://docs.rs/google-consumersurveys2/1.0.7+20170407/google_consumersurveys2/enum.Result.html), should be
+read by you to obtain the media.
+If such a method also supports a [Response Result](https://docs.rs/google-consumersurveys2/1.0.7+20170407/google_consumersurveys2/trait.ResponseResult.html), it will return that by default.
+You can see it as meta-data for the actual media. To trigger a media download, you will have to set up the builder by making
+this call: `.param("alt", "media")`.
+
+Methods supporting uploads can do so using up to 2 different protocols: 
+*simple* and *resumable*. The distinctiveness of each is represented by customized 
+`doit(...)` methods, which are then named `upload(...)` and `upload_resumable(...)` respectively.
+
+## Customization and Callbacks
+
+You may alter the way an `doit()` method is called by providing a [delegate](https://docs.rs/google-consumersurveys2/1.0.7+20170407/google_consumersurveys2/trait.Delegate.html) to the 
+[Method Builder](https://docs.rs/google-consumersurveys2/1.0.7+20170407/google_consumersurveys2/trait.CallBuilder.html) before making the final `doit()` call. 
+Respective methods will be called to provide progress information, as well as determine whether the system should 
+retry on failure.
+
+The [delegate trait](https://docs.rs/google-consumersurveys2/1.0.7+20170407/google_consumersurveys2/trait.Delegate.html) is default-implemented, allowing you to customize it with minimal effort.
+
+## Optional Parts in Server-Requests
+
+All structures provided by this library are made to be [enocodable](https://docs.rs/google-consumersurveys2/1.0.7+20170407/google_consumersurveys2/trait.RequestValue.html) and 
+[decodable](https://docs.rs/google-consumersurveys2/1.0.7+20170407/google_consumersurveys2/trait.ResponseResult.html) via *json*. Optionals are used to indicate that partial requests are responses 
+are valid.
+Most optionals are are considered [Parts](https://docs.rs/google-consumersurveys2/1.0.7+20170407/google_consumersurveys2/trait.Part.html) which are identifiable by name, which will be sent to 
+the server to indicate either the set parts of the request or the desired parts in the response.
+
+## Builder Arguments
+
+Using [method builders](https://docs.rs/google-consumersurveys2/1.0.7+20170407/google_consumersurveys2/trait.CallBuilder.html), you are able to prepare an action call by repeatedly calling it's methods.
+These will always take a single argument, for which the following statements are true.
+
+* [PODs][wiki-pod] are handed by copy
+* strings are passed as `&str`
+* [request values](https://docs.rs/google-consumersurveys2/1.0.7+20170407/google_consumersurveys2/trait.RequestValue.html) are moved
+
+Arguments will always be copied or cloned into the builder, to make them independent of their original life times.

+The `datastore1` command-line interface *(CLI)* allows to use most features of the *Google datastore* service from the comfort of your terminal.
+
+By default all output is printed to standard out, but flags can be set to direct it into a file independent of your shell's
+capabilities. Errors will be printed to standard error, and cause the program's exit code to be non-zero.
+
+If data-structures are requested, these will be returned as pretty-printed JSON, to be useful as input to other tools.
+
+Everything else about the *datastore* API can be found at the
+[official documentation site](https://cloud.google.com/datastore/).
+
+# Installation and Source Code
+
+Install the command-line interface with cargo using:
+
+```bash
+cargo install google-datastore1-cli
+```
+
+Find the source code [on github](https://github.com/Byron/google-apis-rs/tree/master/gen/datastore1-cli).
+
+# Usage
+
+This documentation was generated from the *datastore* API at revision *20171205*. The CLI is at version *1.0.7*.

+            a user-writable directory that we will create during the first invocation.
+            [default: ~/.google-service-cli]
+  --debug
+            Output all server communication to standard error. `tx` and `rx` are placed
+            into the same stream.
+  --debug-auth
+            Output all communication related to authentication to standard error. `tx`
+            and `rx` are placed into the same stream.
+
+```
+
+# Configuration
+
+The program will store all persistent data in the `~/.google-service-cli` directory in *JSON* files prefixed with `datastore1-`.  You can change the directory used to store configuration with the `--config-dir` flag on a per-invocation basis.
+
+More information about the various kinds of persistent data are given in the following paragraphs.
+
+# Authentication
+
+Most APIs require a user to authenticate any request. If this is the case, the [scope][scopes] determines the 
+set of permissions granted. The granularity of these is usually no more than *read-only* or *full-access*.
+
+If not set, the system will automatically select the smallest feasible scope, e.g. when invoking a
+method that is read-only, it will ask only for a read-only scope. 
+You may use the `--scope` flag to specify a scope directly. 
+All applicable scopes are documented in the respective method's CLI documentation.
+
+The first time a scope is used, the user is asked for permission. Follow the instructions given 
+by the CLI to grant permissions, or to decline.
+
+If a scope was authenticated by the user, the respective information will be stored as *JSON* in the configuration
+directory, e.g. `~/.google-service-cli/datastore1-token-<scope-hash>.json`. No manual management of these tokens
+is necessary.
+
+To revoke granted authentication, please refer to the [official documentation][revoke-access].
+
+# Application Secrets
+
+In order to allow any application to use Google services, it will need to be registered using the 
+[Google Developer Console][google-dev-console]. APIs the application may use are then enabled for it
+one by one. Most APIs can be used for free and have a daily quota.
+
+To allow more comfortable usage of the CLI without forcing anyone to register an own application, the CLI
+comes with a default application secret that is configured accordingly. This also means that heavy usage
+all around the world may deplete the daily quota.
+
+You can workaround this limitation by putting your own secrets file at this location: 
+`~/.google-service-cli/datastore1-secret.json`, assuming that the required *datastore* API 
+was enabled for it. Such a secret file can be downloaded in the *Google Developer Console* at 
+*APIs & auth -> Credentials -> Download JSON* and used as is.
+
+Learn more about how to setup Google projects and enable APIs using the [official documentation][google-project-new].
+
+
+# Debugging
+
+Even though the CLI does its best to provide usable error messages, sometimes it might be desirable to know
+what exactly led to a particular issue. This is done by allowing all client-server communication to be 
+output to standard error *as-is*.
+
+The `--debug` flag will print all client-server communication to standard error, whereas the `--debug-auth` flag
+will cause all communication related to authentication to standard error.
+If the `--debug` flag is set, error-results will be debug-printed, possibly yielding more information about the 
+issue at hand.
+
+You may consider redirecting standard error into a file for ease of use, e.g. `datastore1 --debug <resource> <method> [options] 2>debug.txt`.

+The `google-datastore1` library allows access to all features of the *Google datastore* service.
+
+This documentation was generated from *datastore* crate version *1.0.7+20171205*, where *20171205* is the exact revision of the *datastore:v1* schema built by the [mako](http://www.makotemplates.org/) code generator *v1.0.7*.
+
+Everything else about the *datastore* *v1* API can be found at the
+[official documentation site](https://cloud.google.com/datastore/).
+# Features
+
+Handle the following *Resources* with ease from the central [hub](https://docs.rs/google-datastore1/1.0.7+20171205/google_datastore1/struct.Datastore.html) ... 
+
+* projects
+ * [*allocate ids*](https://docs.rs/google-datastore1/1.0.7+20171205/google_datastore1/struct.ProjectAllocateIdCall.html), [*begin transaction*](https://docs.rs/google-datastore1/1.0.7+20171205/google_datastore1/struct.ProjectBeginTransactionCall.html), [*commit*](https://docs.rs/google-datastore1/1.0.7+20171205/google_datastore1/struct.ProjectCommitCall.html), [*lookup*](https://docs.rs/google-datastore1/1.0.7+20171205/google_datastore1/struct.ProjectLookupCall.html), [*operations cancel*](https://docs.rs/google-datastore1/1.0.7+20171205/google_datastore1/struct.ProjectOperationCancelCall.html), [*operations delete*](https://docs.rs/google-datastore1/1.0.7+20171205/google_datastore1/struct.ProjectOperationDeleteCall.html), [*operations get*](https://docs.rs/google-datastore1/1.0.7+20171205/google_datastore1/struct.ProjectOperationGetCall.html), [*operations list*](https://docs.rs/google-datastore1/1.0.7+20171205/google_datastore1/struct.ProjectOperationListCall.html), [*reserve ids*](https://docs.rs/google-datastore1/1.0.7+20171205/google_datastore1/struct.ProjectReserveIdCall.html), [*rollback*](https://docs.rs/google-datastore1/1.0.7+20171205/google_datastore1/struct.ProjectRollbackCall.html) and [*run query*](https://docs.rs/google-datastore1/1.0.7+20171205/google_datastore1/struct.ProjectRunQueryCall.html)
+
+
+
+
+# Structure of this Library
+
+The API is structured into the following primary items:
+
+* **[Hub](https://docs.rs/google-datastore1/1.0.7+20171205/google_datastore1/struct.Datastore.html)**
+    * a central object to maintain state and allow accessing all *Activities*
+    * creates [*Method Builders*](https://docs.rs/google-datastore1/1.0.7+20171205/google_datastore1/trait.MethodsBuilder.html) which in turn
+      allow access to individual [*Call Builders*](https://docs.rs/google-datastore1/1.0.7+20171205/google_datastore1/trait.CallBuilder.html)
+* **[Resources](https://docs.rs/google-datastore1/1.0.7+20171205/google_datastore1/trait.Resource.html)**
+    * primary types that you can apply *Activities* to
+    * a collection of properties and *Parts*
+    * **[Parts](https://docs.rs/google-datastore1/1.0.7+20171205/google_datastore1/trait.Part.html)**
+        * a collection of properties
+        * never directly used in *Activities*
+* **[Activities](https://docs.rs/google-datastore1/1.0.7+20171205/google_datastore1/trait.CallBuilder.html)**
+    * operations to apply to *Resources*
+
+All *structures* are marked with applicable traits to further categorize them and ease browsing.
+
+Generally speaking, you can invoke *Activities* like this:
+
+```Rust,ignore
+let r = hub.resource().activity(...).doit()
+```
+
+Or specifically ...
+
+```ignore
+let r = hub.projects().operations_delete(...).doit()
+let r = hub.projects().operations_cancel(...).doit()
+```
+
+The `resource()` and `activity(...)` calls create [builders][builder-pattern]. The second one dealing with `Activities` 
+supports various methods to configure the impending operation (not shown here). It is made such that all required arguments have to be 
+specified right away (i.e. `(...)`), whereas all optional ones can be [build up][builder-pattern] as desired.
+The `doit()` method performs the actual communication with the server and returns the respective result.
+
+# Usage
+
+## Setting up your Project
+
+To use this library, you would put the following lines into your `Cargo.toml` file:
+
+```toml
+[dependencies]
+google-datastore1 = "*"
+```
+
+## A complete example
+
+```Rust
+extern crate hyper;
+extern crate hyper_rustls;
+extern crate yup_oauth2 as oauth2;
+extern crate google_datastore1 as datastore1;
+use datastore1::{Result, Error};
+use std::default::Default;
+use oauth2::{Authenticator, DefaultAuthenticatorDelegate, ApplicationSecret, MemoryStorage};
+use datastore1::Datastore;
+
+// Get an ApplicationSecret instance by some means. It contains the `client_id` and 
+// `client_secret`, among other things.
+let secret: ApplicationSecret = Default::default();
+// Instantiate the authenticator. It will choose a suitable authentication flow for you, 
+// unless you replace  `None` with the desired Flow.
+// Provide your own `AuthenticatorDelegate` to adjust the way it operates and get feedback about 
+// what's going on. You probably want to bring in your own `TokenStorage` to persist tokens and
+// retrieve them from storage.
+let auth = Authenticator::new(&secret, DefaultAuthenticatorDelegate,
+                              hyper::Client::with_connector(hyper::net::HttpsConnector::new(hyper_rustls::TlsClient::new())),
+                              <MemoryStorage as Default>::default(), None);
+let mut hub = Datastore::new(hyper::Client::with_connector(hyper::net::HttpsConnector::new(hyper_rustls::TlsClient::new())), auth);
+// You can configure optional parameters by calling the respective setters at will, and
+// execute the final call using `doit()`.
+// Values shown here are possibly random and not representative !
+let result = hub.projects().operations_delete("name")
+             .doit();
+
+match result {
+    Err(e) => match e {
+        // The Error enum provides details about what exactly happened.
+        // You can also just use its `Debug`, `Display` or `Error` traits
+         Error::HttpError(_)
+        |Error::MissingAPIKey
+        |Error::MissingToken(_)
+        |Error::Cancelled
+        |Error::UploadSizeLimitExceeded(_, _)
+        |Error::Failure(_)
+        |Error::BadRequest(_)
+        |Error::FieldClash(_)
+        |Error::JsonDecodeError(_, _) => println!("{}", e),
+    },
+    Ok(res) => println!("Success: {:?}", res),
+}
+
+```
+## Handling Errors
+
+All errors produced by the system are provided either as [Result](https://docs.rs/google-datastore1/1.0.7+20171205/google_datastore1/enum.Result.html) enumeration as return value of 
+the doit() methods, or handed as possibly intermediate results to either the 
+[Hub Delegate](https://docs.rs/google-datastore1/1.0.7+20171205/google_datastore1/trait.Delegate.html), or the [Authenticator Delegate](https://docs.rs/yup-oauth2/*/yup_oauth2/trait.AuthenticatorDelegate.html).
+
+When delegates handle errors or intermediate values, they may have a chance to instruct the system to retry. This 
+makes the system potentially resilient to all kinds of errors.
+
+## Uploads and Downloads
+If a method supports downloads, the response body, which is part of the [Result](https://docs.rs/google-datastore1/1.0.7+20171205/google_datastore1/enum.Result.html), should be
+read by you to obtain the media.
+If such a method also supports a [Response Result](https://docs.rs/google-datastore1/1.0.7+20171205/google_datastore1/trait.ResponseResult.html), it will return that by default.
+You can see it as meta-data for the actual media. To trigger a media download, you will have to set up the builder by making
+this call: `.param("alt", "media")`.
+
+Methods supporting uploads can do so using up to 2 different protocols: 
+*simple* and *resumable*. The distinctiveness of each is represented by customized 
+`doit(...)` methods, which are then named `upload(...)` and `upload_resumable(...)` respectively.
+
+## Customization and Callbacks
+
+You may alter the way an `doit()` method is called by providing a [delegate](https://docs.rs/google-datastore1/1.0.7+20171205/google_datastore1/trait.Delegate.html) to the 
+[Method Builder](https://docs.rs/google-datastore1/1.0.7+20171205/google_datastore1/trait.CallBuilder.html) before making the final `doit()` call. 
+Respective methods will be called to provide progress information, as well as determine whether the system should 
+retry on failure.
+
+The [delegate trait](https://docs.rs/google-datastore1/1.0.7+20171205/google_datastore1/trait.Delegate.html) is default-implemented, allowing you to customize it with minimal effort.
+
+## Optional Parts in Server-Requests
+
+All structures provided by this library are made to be [enocodable](https://docs.rs/google-datastore1/1.0.7+20171205/google_datastore1/trait.RequestValue.html) and 
+[decodable](https://docs.rs/google-datastore1/1.0.7+20171205/google_datastore1/trait.ResponseResult.html) via *json*. Optionals are used to indicate that partial requests are responses 
+are valid.
+Most optionals are are considered [Parts](https://docs.rs/google-datastore1/1.0.7+20171205/google_datastore1/trait.Part.html) which are identifiable by name, which will be sent to 
+the server to indicate either the set parts of the request or the desired parts in the response.
+
+## Builder Arguments
+
+Using [method builders](https://docs.rs/google-datastore1/1.0.7+20171205/google_datastore1/trait.CallBuilder.html), you are able to prepare an action call by repeatedly calling it's methods.
+These will always take a single argument, for which the following statements are true.
+
+* [PODs][wiki-pod] are handed by copy
+* strings are passed as `&str`
+* [request values](https://docs.rs/google-datastore1/1.0.7+20171205/google_datastore1/trait.RequestValue.html) are moved
+
+Arguments will always be copied or cloned into the builder, to make them independent of their original life times.
