Trait Host

pub trait Host {
    // Required methods
    fn now(&mut self) -> Instant;
    fn resolution(&mut self) -> Duration;
    fn subscribe_instant(&mut self, when: Instant) -> Resource<Pollable>;
    fn subscribe_duration(&mut self, when: Duration) -> Resource<Pollable>;
}

Required Methods

fn now(&mut self) -> Instant

Read the current value of the clock.

The clock is monotonic, therefore calling this function repeatedly will produce a sequence of non-decreasing values.

fn resolution(&mut self) -> Duration

Query the resolution of the clock. Returns the duration of time corresponding to a clock tick.

fn subscribe_instant(&mut self, when: Instant) -> Resource<Pollable>

Create a pollable which will resolve once the specified instant has occurred.

fn subscribe_duration(&mut self, when: Duration) -> Resource<Pollable>

Create a pollable that will resolve after the specified duration has elapsed from the time this function is invoked.
