Trait for working with generic timer wheel implementations.

Required Methods

fn insert_timeout(
    &mut self,
    timeout: Duration,
    item: T
) -> PendulumResult<Token, T>

Insert a timeout with the given duration and the given item into the Pendulum.

fn remove_timeout(&mut self, token: Token) -> Option<T>

Removes the timeout corresponding with the given Token, if one exists.

fn expired_timeout(&mut self) -> Option<T>

Retrieve the next expired timeout from the Pendulum.

This is a non-blocking operation.

fn tick(&mut self)

Tick the Pendulum once.

fn tick_duration(&self) -> Duration

Configured tick duration for this Pendulum.

fn max_capacity(&self) -> usize

Configured max timeout capacity for this Pendulum.

fn max_timeout(&self) -> Duration

Configured maximum timeout for this Pendulum.
