[−][src]Struct futures::sink::Buffer
Sink for the Sink::buffer
combinator, which buffers up to some fixed
number of values when the underlying sink is unable to accept them.
Methods
impl<S: Sink> Buffer<S>
[src]
pub fn get_ref(&self) -> &S
[src]
Get a shared reference to the inner sink.
pub fn get_mut(&mut self) -> &mut S
[src]
Get a mutable reference to the inner sink.
pub fn into_inner(self) -> S
[src]
Consumes this combinator, returning the underlying sink.
Note that this may discard intermediate state of this combinator, so care should be taken to avoid losing resources when this is called.
Trait Implementations
impl<S> Stream for Buffer<S> where
S: Sink + Stream,
[src]
S: Sink + Stream,
type Item = S::Item
The type of item this stream will yield on success.
type Error = S::Error
The type of error this stream may generate.
