[−][src]Struct futures::stream::Forward
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
U: Sink<SinkItem = T::Item>,
T: Stream,
T::Error: From<U::SinkError>,
[src][−]
U: Sink<SinkItem = T::Item>,
T: Stream,
T::Error: From<U::SinkError>,
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.
