Trait Implementations

impl<I, E> Sink for TestSender<I, E>

type SinkItem = Result<I, E>

The type of value that the sink accepts.

type SinkError = Never

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

fn poll_ready(&mut self, cx: &mut Context) -> Poll<(), Self::SinkError>

Attempts to prepare the Sink to receive a value.

fn start_send(&mut self, item: Self::SinkItem) -> Result<(), Self::SinkError>

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

fn poll_flush(&mut self, cx: &mut Context) -> Poll<(), Self::SinkError>

Flush any remaining output from this sink.

fn poll_close(&mut self, cx: &mut Context) -> Poll<(), Self::SinkError>

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