Trait Clock 

pub trait Clock {
    // Required methods
    fn now() -> Self;
    fn set_scaling_factor(&mut self, scaling: usize);
    fn duration_since(&self, earlier: Self) -> Duration;
}

A trait for time sources. This allows methods to be generic over different ways of measuring time.

Required Methods

fn now() -> Self

Get a timestamp.

fn set_scaling_factor(&mut self, scaling: usize)

Set a scaling factor, which can be used to convert a difference of timestamps to seconds.

fn duration_since(&self, earlier: Self) -> Duration

Get the duration from earlier to self as a std::time::Duration.

Panics

If earlier is not earlier.

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.
