Async WebSocket usage.
This library is an implementation of WebSocket handshakes and streams. It is based on the crate which implements all required WebSocket protocol logic. So this crate basically just brings tokio support / tokio integration to it.
Each WebSocket stream implements the required Stream and Sink traits,
so the socket is just a stream of messages coming in and going out.
This crate primarily exports this ability through two extension traits,
ClientHandshakeExt and ServerHandshakeExt. These traits augment the
functionality provided by the tungestenite crate, on which this crate is
built. Configuration is done through tungestenite crate as well.
