Trait futures_core::future::FusedFuture

source · [−]
pub trait FusedFuture: Future {
    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 polled again.

Required methods

Returns true if the underlying future should no longer be polled.
