Trait Implementations

impl<F> Debug for IntoStream<F> where
    Once<F>: Debug, 

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

Formats the value using the given formatter.

impl<F> FusedStream for IntoStream<F> where
    Once<F>: FusedStream, 

fn is_terminated(&self) -> bool

Returns true if the stream should no longer be polled.

impl<F> Stream for IntoStream<F> where
    Once<F>: Stream, 

type Item = <Once<F> as Stream>::Item

Values yielded by the stream.

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

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

Returns the bounds on the remaining length of the stream.

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