Struct futures_util::future::FlattenStream

pub struct FlattenStream<F>where
    F: Future,{ /* private fields */ }

Stream for the flatten_stream method.

Trait Implementations

impl<F> Debug for FlattenStream<F>where
    Flatten<F, <F as Future>::Output>: Debug,
    F: Future,

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

Formats the value using the given formatter.

impl<F> FusedStream for FlattenStream<F>where
    Flatten<F, <F as Future>::Output>: FusedStream,
    F: Future,

fn is_terminated(&self) -> bool

Returns true if the stream should no longer be polled.

impl<F> Stream for FlattenStream<F>where
    Flatten<F, <F as Future>::Output>: Stream,
    F: Future,

type Item = <Flatten<F, <F as Future>::Output> as Stream>::Item

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.

impl<'__pin, F> Unpin for FlattenStream<F>where
    __Origin<'__pin, F>: Unpin,
    F: Future,
