* Rewrite tarpc on top of tokio. * Add examples * Move error types to their own module. Also, cull unused error variants. * Remove unused fn * Remove CanonicalRpcError* types. They're 100% useless. * Track tokio master (WIP) * The great error revamp. Removed the canonical rpc error type. Instead, the user declares the error type for each rpc: In the above example, the error type is Baz. Declaring an error is optional; if none is specified, it defaults to Never, a convenience struct that wraps the never type (exclamation mark) to impl Serialize, Deserialize, Error, etc. Also adds the convenience type StringError for easily using a String as an error type. * Add missing license header * Minor cleanup * Rename StringError => Message * Create a sync::Connect trait. Along with this, the existing Connect trait moves to future::Connect. The future and sync modules are reexported from the crate root. Additionally, the utility errors Never and Message are no longer reexported from the crate root. * Update readme * Track tokio/futures master. Add a Spawn utility trait to replace the removed forget. * Fix pre-push hook * Add doc comment to SyncServiceExt. * Fix up some documentation * Track tokio-proto master * Don't set tcp nodelay * Make future::Connect take an associated type for the future. * Unbox FutureClient::connect return type * Use type alias instead of newtype struct for ClientFuture * Fix benches/latency.rs * Write a plugin to convert lower_snake_case idents/types to UpperCamelCase. Use it to add associated types to FutureService instead of boxing the return futures. * Specify plugin = true in snake_to_camel/Cargo.toml. Weird things happen otherwise. * Add clippy.toml
