[][src]Struct tokio::prelude::stream::Forward

#[must_use = "futures do nothing unless polled"]
pub struct Forward<T, U> where
    T: Stream
{ /* fields omitted */ }

Future for the Stream::forward combinator, which sends a stream of values to a sink and then waits until the sink has fully flushed those values.

Methods

impl<T, U> Forward<T, U> where
    T: Stream,
    U: Sink<SinkItem = <T as Stream>::Item>,
    <T as Stream>::Error: From<<U as Sink>::SinkError>, 
[src]

pub fn sink_ref(&self) -> Option<&U>[src]

Get a shared reference to the inner sink. If this combinator has already been polled to completion, None will be returned.

pub fn sink_mut(&mut self) -> Option<&mut U>[src]

Get a mutable reference to the inner sink. If this combinator has already been polled to completion, None will be returned.

pub fn stream_ref(&self) -> Option<&T>[src]

Get a shared reference to the inner stream. If this combinator has already been polled to completion, None will be returned.

pub fn stream_mut(&mut self) -> Option<&mut T>[src]

Get a mutable reference to the inner stream. If this combinator has already been polled to completion, None will be returned.
