Struct ordered_stream::Filter

pub struct Filter<S, F> { /* fields omitted */ }

A stream for the filter function.

Trait Implementations

impl<S: Debug, F: Debug> Debug for Filter<S, F>

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

Formats the value using the given formatter.

impl<S, F> OrderedStream for Filter<S, F> where
    S: OrderedStream,
    F: FnMut(&S::Data) -> bool, 

type Data = S::Data

The unordered data carried by this stream

type Ordering = S::Ordering

The type ordered by this stream.

fn poll_next_before(
    self: Pin<&mut Self>,
    cx: &mut Context<'_>,
    before: Option<&Self::Ordering>
) -> Poll<PollResult<Self::Ordering, Self::Data>>

Attempt to pull out the next value of this stream, registering the current task for wakeup if needed, and returning NoneBefore if it is known that the stream will not produce any more values ordered before the given point.

fn position_hint(&self) -> Option<MaybeBorrowed<'_, Self::Ordering>>

The minimum value of the ordering for any future items.

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

Returns the bounds on the remaining length of the stream.

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