Struct ChannelSink 

pub struct ChannelSink { /* private fields */ }

A sink that sends WebSocket messages through a channel.

This implements Sink<Message> so it can be used with send_frame and other functions that expect a WebSocket writer.

Implementations

impl ChannelSink

pub fn new(tx: ModelTaskTx, thread_id: ThreadId) -> Self

pub async fn done(&self, response: Option<String>)

Signal that the task completed successfully.

pub async fn error(&self, message: String)

Signal that the task failed.

Trait Implementations

impl Sink<Message> for ChannelSink

type Error = SendError<ModelTaskMessage>

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.
