Struct zbus::azync::MessageSink[−][src]

pub struct MessageSink { /* fields omitted */ }

Expand description

A futures_sink::Sink implementation that consumes Message instances.

Use Connection::sink to create an instance of this type.

Caveats

At the moment, a simultaneous flush request from multiple tasks/threads could potentially create a busy loop, thus wasting CPU time. This limitation may be removed in the future.

Trait Implementations

impl Sink<Message> for MessageSink[src]

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<()>>[src]

Attempts to prepare the Sink to receive a value. Read more

fn start_send(self: Pin<&mut Self>, msg: Message) -> Result<()>[src]

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(())). Read more

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

Flush any remaining output from this sink. Read more

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

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