Breaking Changes

• All usage of async traits (Future, Stream,
  AsyncRead, AsyncWrite, etc) are updated to newer versions.

(8f4b05ae)

• All usage of hyper::Chunk should be replaced with
  bytes::Bytes (or hyper::body::Bytes).

(5a598757)

• Using a Body as a Stream, and constructing one via
  Body::wrap_stream, require enabling the stream feature.

(511ea388)

• Calls to GaiResolver::new and HttpConnector::new no
  longer should pass an integer argument for the number of threads.

(049b5132)

• Connectors no longer return a tuple of
  (T, Connected), but a single T: Connection.

(4d7a2266)

• All usage of hyper::client::connect::Destination
  should be replaced with http::Uri.

(319e8aee)

• All usage of hyper::body::Payload should be replaced
  with hyper::body::HttpBody.

(c63728eb)

• Any type passed to the executor builder methods must
  now implement hyper::rt::Executor.

  hyper::rt::spawn usage should be replaced with tokio::task::spawn.

  hyper::rt::run usage should be replaced with #[tokio::main] or
  managing a tokio::runtime::Runtime manually.

(6ae5889f)

• The Resolve trait is gone. All custom resolvers should
  implement tower::Service instead.

  The error type of HttpConnector has been changed away from
  std::io::Error.

(9d9233ce)

• Any manual implementations of Connect must instead
  implement tower::Service<Uri>.

(d67e49f1)

• The server's behavior will now by default close
  connections when receiving a read EOF. To allow for clients to close
  the read half, call http1_half_close(true) when configuring a
  server.

(7e31fd88)

• Passing a Stream to Server::builder or
  Http::serve_incoming must be changed to pass an Accept instead. The
  stream optional feature can be enabled, and then a stream can be
  converted using hyper::server::accept::from_stream.

(b3e55062)

• Usage of send_data should either be changed to
  async/await or use try_send_data.
