Expand description

Implements methods used for setting and waiting on timers on a dispatcher.

Required Methods§

Source

fn after_deadline(&self, deadline: MonotonicInstant) -> AfterDeadline ⓘ

Returns a future that will fire when after the given deadline time.

This can be used instead of the fuchsia-async timer primitives in situations where there isn’t a currently active fuchsia-async executor running on that dispatcher for some reason (ie. the rust code does not own the dispatcher) or for cases where the small overhead of fuchsia-async compatibility is too much.

§Panics

If the dispatcher pointed to by self is not available right now (like [CurrentDispatcher]) on a thread with no current dispatcher set, this function will panic. You can use Self::try_after_deadline to handle the condition where there is no current dispatcher, or if you’re trying to run it on the current dispatcher you may want to use AfterDeadline::new instead.

Source

fn try_after_deadline( &self, deadline: MonotonicInstant, ) -> Option<AfterDeadline>

Returns a future that will fire when after the given deadline time.

This can be used instead of the fuchsia-async timer primitives in situations where there isn’t a currently active fuchsia-async executor running on that dispatcher for some reason (ie. the rust code does not own the dispatcher) or for cases where the small overhead of fuchsia-async compatibility is too much.
