Adds `tonic::Extensions` which is a newtype around `http::Extensions`.
Request extensions can be set by interceptors with
`Request::extensions_mut` and retrieved from RPCs with
`Request::extensions`. Extensions can also be set in tower middleware
and will be carried through to the RPC.
Since response extensions cannot be set by interceptors the main use
case is to set them in RPCs and retrieve them in tower middlewares.
Figured that might be useful.
Fixes https://github.com/hyperium/tonic/issues/255
Doing
```rust
let clone = self.inner.clone();
Box::pin(async move {
let response = clone.call(request).await?;
Ok(response)
})
```
If `self.inner` is (or contains) a `tower::buffer::Buffer` might panic.
That is because cloning a `Buffer` drops the permit that was acquired in
`poll_ready`, meaning it is no longer ready and panic in `call`.
The solution is to use `mem::replace` to take the ready service and pass
that into the async block.

* Upgrade Tonic to Tokio 1.0
Work in progress for updating Tonic to Tokio 1.0. Since tower has not
been released to crates.io, a git dependency is taken instead.
* Upgrade Tonic to Tokio 1.0 phase 2
* tonic: remove tower-* deps
* Apply suggestions from code review

* transport: impl Service for Channel instead of GrpcService
This adds tower::Service impl for tonic::transport::Channel
and removes GrpcService impl declaration.
Channel still implements GrpcService, thanks to the general
impl declaration of GrpcService for types who implement Service.
Fixes#481.
* examples: stop using GrpcService to avoid ambiguity
* examples: add timeout example
* examples: update to `tracing` 0.1.14, use `#[instrument]`
Now that `tracing-attributes`'s `#[instrument]` macro plays nicely with
`async-trait`, we can update the tracing example to use `instrument`.
This lets us simplify the events emitted in the example.

* Propagate errors in tls_config instead of unwrap
Ran into `tls_connector` failing and causing our app to panic and shutdown as it seems there wasn't any way to avoid panicking in `tls_config`.
So after talking to @LucioFranco briefly `tls_config` now returns a `Result` instead and propagates errors to the caller, where they can be handled.
* Fix compile warning when tls feature is disabled
* Create an example of an autoreloading server
* Document the autoreloading server example
* Format autoreloading server example
* Add note about cargo-watch in the examples readme
This commit adds a new crate `tonic-health` which implements the
[standard GRPC Health Checking][checking] protocol.
Currently there is only a server implementation, though others have
alluded in the discussion in #135 that client implementations exist
which could also be imported as necessary.
A example server has also been added - once the client work is done a
client for this should be added also.
[checking]: https://github.com/grpc/grpc/blob/master/doc/health-checking.mdFixes#135.
