Trait futures_core::stream::FusedStream
source · [−]pub trait FusedStream: Stream {
fn is_terminated(&self) -> bool;
}Expand description
A stream which tracks whether or not the underlying stream should no longer be polled.
is_terminated will return true if a future should no longer be polled.
Usually, this state occurs after poll_next (or try_poll_next) returned
Poll::Ready(None). However, is_terminated may also return true if a
stream has become inactive and can no longer make progress and should be
ignored or dropped rather than being polled again.
