* Extend snake_to_camel plugin to replace {} in the doc string with the origin snake-cased ident.
Also, track tokio-rs master.
This is really ad-hoc, undiscoverable, and unintuitive, but there's no way to programmatically create doc strings
in regular code, and I want to produce better doc strings for the associated types.
Given `fn foo_bar`:
Before: `/// The type of future returned by the function of the same name.`
After: ``/// The type of future returned by `{}`.``
=> `/// The type of future returned by foo_bar.`
* Fix some docs
* Use a helper fn on pipeline::Frame instead of handrolled match.
* Don't hide docs for ClientFuture.
It's exposed in the Connect impl of FutureService -- the tradeoff for not generating *another* item -- and hiding it breaks doc links.
* Formatting
* Rename snake_to_camel plugin => tarpc-plugins
* Update README
* Mangle a lot of names in macro expansion.
To lower the chance of any issues, prefix idents in service expansion with __tarpc_service.
In future_enum, prefix with __future_enum. The pattern is basically __macro_name_ident.
Any imported enum variant will conflict with a let binding or a function arg, so we basically
can't use any generic idents at all. Example:
enum Req { request(..) }
use self::Req::request;
fn make_request(request: Request) { ... }
^^^^^^^ conflict here
Additionally, suffix generated associated types with Fut to avoid conflicts with camelcased rpcs.
Why someone would do that, I don't know, but we shouldn't allow that wart.
