Trait futures_core::future::FusedFuture

source ·
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 polled again.
