pub trait FusedFuture: Future {
// Required method
fn is_terminated(&self) -> bool;
}
Expand description
A future which tracks whether or not the underlying future should no longer be polled.
is_terminated
will return true
if a future should no longer be polled.
Usually, this state occurs after poll
(or try_poll
) returned
Poll::Ready
. However, is_terminated
may also return true
if a future
has become inactive and can no longer make progress and should be ignored
or dropped rather than being poll
ed again.
Required Methods§

fn is_terminated(&self) -> bool

if the underlying future should no longer be polled.
