Trait vector::sinks::prelude::future::FusedFuture
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.
Required Methods§
fn is_terminated(&self) -> bool
fn is_terminated(&self) -> bool
