Trait Clock 

pub trait Clock: Sized {
    type T: TimeInt + Hash;

    const SCALING_FACTOR: Fraction;

    // Required method
    fn try_now(&self) -> Result<Instant<Self>, Error>;

    // Provided method
    fn new_timer<Dur>(
        &self,
        duration: Dur,
    ) -> Timer<'_, OneShot, Armed, Self, Dur>
       where Dur: FixedPoint + Duration { ... }
}

The Clock trait provides an abstraction for hardware-specific timer peripherals, external timer devices, RTCs, etc.

The Clock is characterized by an inner unsigned integer storage type (either u32 or u64), a u32/u32 Fraction defining the duration (in seconds) of one count of the Clock, and a custom error type representing errors that may be generated by the implementation.

In addition to the Clock::try_now() method which returns an Instant, software Timers can be spawned from a Clock object.

Required Associated Constants

const SCALING_FACTOR: Fraction

The duration of one clock tick in seconds, AKA the clock precision.

Required Associated Types

type T: TimeInt + Hash

The type to hold the tick count

Required Methods

fn try_now(&self) -> Result<Instant<Self>, Error>

Get the current Instant

Errors

• Error::NotRunning
• Error::Unspecified

Provided Methods

fn new_timer<Dur>(&self, duration: Dur) -> Timer<'_, OneShot, Armed, Self, Dur>

where Dur: FixedPoint + Duration,

Spawn a new, OneShot Timer from this clock

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
