Struct async_tungstenite::WebSocketStream
source · [−]pub struct WebSocketStream<S> { /* private fields */ }Expand description
A wrapper around an underlying raw stream which implements the WebSocket protocol.
A WebSocketStream<S> represents a handshake that has been completed
successfully and both the server and the client are ready for receiving
and sending data. Message from a WebSocketStream<S> are accessible
through the respective Stream and Sink. Check more information about
them in futures-rs crate documentation or have a look on the examples
and unit tests for this crate.
