Struct futures_util::future::TryFlattenStream

pub struct TryFlattenStream<Fut> where
    Fut: TryFuture,  { /* fields omitted */ }

Future for the try_flatten_stream method.

Trait Implementations

impl<Fut> Debug for TryFlattenStream<Fut> where
    TryFlatten<Fut, Fut::Ok>: Debug,
    Fut: TryFuture, 

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

Formats the value using the given formatter.

impl<Fut> FusedStream for TryFlattenStream<Fut> where
    TryFlatten<Fut, Fut::Ok>: FusedStream,
    Fut: TryFuture, 

fn is_terminated(&self) -> bool

Returns true if the stream should no longer be polled.

impl<Fut> Stream for TryFlattenStream<Fut> where
    TryFlatten<Fut, Fut::Ok>: Stream,
    Fut: TryFuture, 

type Item = <TryFlatten<Fut, Fut::Ok> 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, Fut> Unpin for TryFlattenStream<Fut> where
    __Origin<'__pin, Fut>: Unpin,
    Fut: TryFuture,
