Trait futures_util::stream::FusedStream
source · pub trait FusedStream: Stream {
// Required method
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.
