pub struct Flatten<S: CompletionStream> { /* fields omitted */ }

Stream for CompletionStreamExt::flatten.

Trait Implementations

impl<S: Clone + CompletionStream> Clone for Flatten<S> where
    S::Item: Clone, 

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<S, U> CompletionStream for Flatten<S> where
    S: CompletionStream<Item = U>,
    U: CompletionStream, 

type Item = U::Item

Values yielded by the stream.

unsafe 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.

unsafe fn poll_cancel(self: Pin<&mut Self>, cx: &mut Context<'_>) -> Poll<()>

Attempt to cancel the stream, registering the current task for wakeup if it has not finished cancelling yet.

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

Returns the bounds on the remaining length of the stream.

impl<S: Debug + CompletionStream> Debug for Flatten<S> where
    S::Item: Debug, 

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

Formats the value using the given formatter.

impl<S, U> Stream for Flatten<S> where
    S: CompletionStream<Item = U> + Stream<Item = U>,
    U: CompletionStream + Stream<Item = <U as CompletionStream>::Item>, 

type Item = Self::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, S: CompletionStream> Unpin for Flatten<S> where
    __Origin<'__pin, S>: Unpin,
