Struct futures::sink::Send

#[must_use = "futures do nothing unless polled"]
pub struct Send<S> where
    S: Sink,  { /* fields omitted */ }

Future for the Sink::send combinator, which sends a value to a sink and then waits until the sink has fully flushed.

Methods

impl<S> Send<S> where
    S: Sink, 

pub fn get_ref(&self) -> Option<&S>

Get a shared reference to the inner sink.

Returns None if the future has completed already.

pub fn get_mut(&mut self) -> Option<&mut S>

Get a mutable reference to the inner sink.

Returns None if the future has completed already.

Trait Implementations

impl<S> Debug for Send<S> where
    S: Debug + Sink,
    <S as Sink>::SinkItem: Debug, 

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

Formats the value using the given formatter.

impl<S> Future for Send<S> where
    S: Sink, 

type Item = S

A successful value

type Error = <S as Sink>::SinkError

An error

fn poll(&mut self, cx: &mut Context) -> Result<Async<S>, <S as Sink>::SinkError>

Attempt to resolve the future to a final value, registering the current task for wakeup if the value is not yet available.
