Struct futures_util::stream::PollImmediate

pub struct PollImmediate<S> { /* private fields */ }

Stream for the poll_immediate function.

It will never return Poll::Pending

Trait Implementations

impl<S: Clone> Clone for PollImmediate<S>

fn clone(&self) -> PollImmediate<S>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<S: Debug> Debug for PollImmediate<S>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<S: Stream> FusedStream for PollImmediate<S>

fn is_terminated(&self) -> bool

Returns true if the stream should no longer be polled.

impl<T, S> Stream for PollImmediate<S>where
    S: Stream<Item = T>,

type Item = Poll<T>

Values yielded by the stream.

fn poll_next(
    self: Pin<&mut Self>,
    cx: &mut Context<'_>
) -> Poll<Option<Self::Item>>

Attempt to pull out the next value of this stream, registering the current task for wakeup if the value is not yet available, and returning None if the stream is exhausted.

fn size_hint(&self) -> (usize, Option<usize>)

Returns the bounds on the remaining length of the stream.
