Trait FusedStream
pub trait FusedStream: StreamA 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.
Required Methods
