Struct packet_stream::PsSink

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]> + Debug, 

type SinkItem = (B, PsPacketType, bool)

If the bool is true, the end/error flag gets set.

type SinkError = Error

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

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

Begin the process of sending a value to the sink.

fn poll_complete(&mut self) -> Poll<(), Self::SinkError>

Flush all output from this sink, if necessary.

fn close(&mut self) -> Poll<(), Self::SinkError>

This only closes the packet-stream if necessary, but it does not automatically send a packet signalling the end of the substream.

fn wait(self) -> Wait<Self>

Creates a new object which will produce a synchronous sink.

fn with<U, F, Fut>(self, f: F) -> With<Self, U, F, Fut> where
    F: FnMut(U) -> Fut,
    Fut: IntoFuture<Item = Self::SinkItem>,
    <Fut as IntoFuture>::Error: From<Self::SinkError>, 

Composes a function in front of the sink.

fn with_flat_map<U, F, St>(self, f: F) -> WithFlatMap<Self, U, F, St> where
    F: FnMut(U) -> St,
    St: Stream<Item = Self::SinkItem, Error = Self::SinkError>, 

Composes a function in front of the sink.

fn sink_map_err<F, E>(self, f: F) -> SinkMapErr<Self, F> where
    F: FnOnce(Self::SinkError) -> E, 

Transforms the error returned by the sink.

fn sink_from_err<E>(self) -> SinkFromErr<Self, E> where
    E: From<Self::SinkError>, 

Map this sink's error to any error implementing From for this sink's Error, returning a new sink.

fn buffer(self, amt: usize) -> Buffer<Self>

Adds a fixed-size buffer to the current sink.

fn fanout<S>(self, other: S) -> Fanout<Self, S> where
    S: Sink<SinkItem = Self::SinkItem, SinkError = Self::SinkError>,
    Self::SinkItem: Clone, 

Fanout items to multiple sinks.

fn flush(self) -> Flush<Self>

A future that completes when the sink has finished processing all pending requests.

fn send(self, item: Self::SinkItem) -> Send<Self>

A future that completes after the given item has been fully processed into the sink, including flushing.

fn send_all<S>(self, stream: S) -> SendAll<Self, S> where
    S: Stream<Item = Self::SinkItem>,
    Self::SinkError: From<<S as Stream>::Error>, 

A future that completes after the given stream has been fully processed into the sink, including flushing.
