Struct futures_util::try_future::FlattenSink

pub struct FlattenSink<Fut, Si>(_);

Future for the flatten_sink combinator.

Trait Implementations

impl<Fut: Debug, Si: Debug> Debug for FlattenSink<Fut, Si>

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

Formats the value using the given formatter.

impl<Fut: Unpin, Si: Unpin> Unpin for FlattenSink<Fut, Si>

impl<Fut, Si> Sink for FlattenSink<Fut, Si> where     Fut: TryFuture<Ok = Si>,     Si: Sink<SinkError = Fut::Error>,

type SinkItem = Si::SinkItem

The type of value that the sink accepts.

type SinkError = Si::SinkError

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

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

Attempts to prepare the Sink to receive a value.

fn start_send(     self: PinMut<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(Poll::Ready(())).

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

Flush any remaining output from this sink.

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

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