Struct tokio_websockets::proto::WebSocketStream

pub struct WebSocketStream<T> { /* private fields */ }

A WebSocket stream that full messages can be read from and written to.

The stream implements futures_sink::Sink and futures_core::Stream.

You must use a ClientBuilder or ServerBuilder to obtain a WebSocket stream.

For usage examples, see the top level crate documentation, which showcases a simple echo server and client.

Trait Implementations

impl<T: Debug> Debug for WebSocketStream<T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T> Sink<Message> for WebSocketStream<T>

where T: AsyncRead + AsyncWrite + Unpin,

type Error = Error

The type of value produced by the sink when an error occurs.

fn poll_ready( self: Pin<&mut Self>, cx: &mut Context<'_> ) -> Poll<Result<(), Self::Error>>

Attempts to prepare the Sink to receive a value.

fn start_send(self: Pin<&mut Self>, item: Message) -> Result<(), Self::Error>

Begin the process of sending a value to the sink. Each call to this function must be preceded by a successful call to poll_ready which returned Poll::Ready(Ok(())).

fn poll_flush( self: Pin<&mut Self>, cx: &mut Context<'_> ) -> Poll<Result<(), Self::Error>>

Flush any remaining output from this sink.

fn poll_close( self: Pin<&mut Self>, cx: &mut Context<'_> ) -> Poll<Result<(), Self::Error>>

Flush any remaining output and close this sink, if necessary.

impl<T> Stream for WebSocketStream<T>

where T: AsyncRead + AsyncWrite + Unpin,

type Item = Result<Message, Error>

Values yielded by the stream.

fn poll_next( self: Pin<&mut Self>, cx: &mut Context<'_> ) -> Poll<Option<Self::Item>>

Attempt to pull out the next value of this stream, registering the current task for wakeup if the value is not yet available, and returning None if the stream is exhausted.

fn size_hint(&self) -> (usize, Option<usize>)

Returns the bounds on the remaining length of the stream.
