pub struct PsSink<W: AsyncWrite, B: AsRef<[u8]>> { /* fields omitted */ }

The sink half of a duplex multiplexed over the packet-stream.

Trait Implementations

impl<W, B> Sink for PsSink<W, B> where
    W: AsyncWrite,
    B: AsRef<[u8]>, 

type SinkItem = (B, Metadata)

The type of value that the sink accepts.

type SinkError = Option<IoError>

The error contains a None if an Request, PeerResponse or PsSink errored previously.

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.
