Expand description

A trait which allows futures to be easily wrapped in a timeout.

Provided Methods§

source

fn on_timeout<WT, OT>(self, time: WT, on_timeout: OT) -> OnTimeout<Self, OT> ⓘwhere WT: WakeupTime, OT: FnOnce() -> Self::Output,

Wraps the future in a timeout, calling on_timeout to produce a result when the timeout occurs.

source

fn on_stalled<OS>( self, timeout: Duration, on_stalled: OS ) -> OnStalled<Self, OS> ⓘwhere OS: FnOnce() -> Self::Output,

Wraps the future in a stall-guard, calling on_stalled to produce a result when the future hasn’t been otherwise polled within the timeout. This is a heuristic - spurious wakeups will keep the detection from triggering, and moving all work to external tasks or threads with force the triggering early.
