pub struct Buffered<S>where
S: Stream,
<S as Stream>::Item: IntoFuture,{ /* private fields */ }
Expand description
An adaptor for a stream of futures to execute the futures concurrently, if possible.
This adaptor will buffer up a list of pending futures, and then return their
results in the order that they were pulled out of the original stream. This
is created by the Stream::buffered
method.
Implementations§
source§impl<S> Buffered<S>where

sourcepub fn get_ref(&self) -> &S
pub fn get_ref(&self) -> &S
Acquires a reference to the underlying stream that this combinator is pulling from.
sourcepub fn get_mut(&mut self) -> &mut S
pub fn get_mut(&mut self) -> &mut S
Acquires a mutable reference to the underlying stream that this combinator is pulling from.
Note that care must be taken to avoid tampering with the state of the stream which may otherwise confuse this combinator.
sourcepub fn into_inner(self) -> S
pub fn into_inner(self) -> S
Consumes this combinator, returning the underlying stream.
Note that this may discard intermediate state of this combinator, so care should be taken to avoid losing resources when this is called.
