pub struct SinkMapErr<S, F> { /* fields omitted */ }

Sink for the Sink::sink_map_err combinator.

Trait Implementations

impl<S: Debug, F: Debug> Debug for SinkMapErr<S, F>

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl<S, F, E> Sink for SinkMapErr<S, F> where S: Sink,
        F: FnOnce(S::SinkError) -> E

type SinkItem = S::SinkItem

The type of value that the sink accepts.

type SinkError = E

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>

A method to indicate that no more values will ever be pushed into this sink.

fn wait(self) -> Wait<Self> where Self: Sized

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::Error: From<Self::SinkError>,
        Self: Sized

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, Self: Sized

Transforms the error returned by the sink.

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

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> where Self: Sized

Adds a fixed-size buffer to the current sink.

fn flush(self) -> Flush<Self> where Self: Sized

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

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

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::Error>,
        Self: Sized

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