fn poll_next_before(

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. Read more
