[−][src]Struct ws_stream_tungstenite::WsStream
Takes a WebSocketStream from tokio-tungstenite and implements futures 0.3 AsyncRead/AsyncWrite. Please look at the documentation of the impls for those traits below for details (rustdoc will collapse them).
Methods
impl<S: AsyncRead01 + AsyncWrite01> WsStream<S>
[src]
pub fn new(inner: TTungSocket<S>) -> Self
[src]
Create a new WsStream.
Trait Implementations
impl<S: AsyncRead01 + AsyncWrite01> Debug for WsStream<S>
[src]
impl<S: AsyncRead01 + AsyncWrite01> AsyncRead for WsStream<S>
[src]
When None is returned, it means it is safe to drop the underlying connection.
TODO: can we not just save an IntoAsyncRead on self instead of the TungWebSocket? that way we don't need to duplicate the algorithm here?

impl<S: AsyncRead01 + AsyncWrite01> AsyncWrite for WsStream<S>
[src]
Errors
The following errors can be returned when writing to the stream:
-
io::ErrorKind::NotConnected
: This means that the connection is already closed. You should drop it. It is safe to drop the underlying connection. -
io::ErrorKind::InvalidData
: This means that a tungstenite::error::Capacity occurred. This means that you send in a buffer bigger than the maximum message size configured on the underlying websocket connection. If you did not set it manually, the default for tungstenite is 64MB. -
other std::io::Error's generally mean something went wrong on the underlying transport. Consider these fatal and just drop the connection.
fn poll_write(
self: Pin<&mut Self>,
cx: &mut Context,
buf: &[u8]
) -> Poll<Result<usize>>
[src]
self: Pin<&mut Self>,
cx: &mut Context,
buf: &[u8]
) -> Poll<Result<usize>>
Will always flush the underlying socket. Will always create an entire Websocket message from every write, so call with a sufficiently large buffer if you have performance problems.
