}

A low-level wall-clock timer API.

Required Associated Types

type Id: Hash + Clone + Eq + Ord

A type to uniquely identify any timeout to be scheduled or cancelled.

type State: State<Id = Self::Id>

The type of state to keep for timers.

type Error: Error + Send + Sync + 'static

Error type produced by timer operations.

Required Methods

fn schedule_at( &mut self, deadline: SystemTime, state: Self::State, ) -> Result<(), Self::Error>

Schedule the state to be triggered at the given wall-clock deadline.

fn cancel(&mut self, id: Self::Id) -> Result<(), Self::Error>

Cancel the timer indicated by the unique id.
