Trait Implementations

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

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

Formats the value using the given formatter.

impl<S, F, R> OrderedStream for FilterMap<S, F> where
    S: OrderedStream,
    F: FnMut(S::Data) -> Option<R>, 

type Data = R

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.
