Struct futures_util::stream::RepeatWith

pub struct RepeatWith<F> { /* private fields */ }

An stream that repeats elements of type A endlessly by applying the provided closure F: FnMut() -> A.

This struct is created by the repeat_with() function. See its documentation for more.

Trait Implementations

impl<F: Clone> Clone for RepeatWith<F>

fn clone(&self) -> RepeatWith<F>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<F: Debug> Debug for RepeatWith<F>

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

Formats the value using the given formatter.

impl<A, F: FnMut() -> A> FusedStream for RepeatWith<F>

fn is_terminated(&self) -> bool

Returns true if the stream should no longer be polled.

impl<A, F: FnMut() -> A> Stream for RepeatWith<F>

type Item = A

Values yielded by the stream.

fn poll_next( self: Pin<&mut Self>, _: &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.
