Trait Time 

pub trait Time:
    PartialEq
    + PartialOrd
    + Clone
    + Copy {
    type Duration: Default + PartialEq + PartialOrd + Clone + Copy;

    // Required methods
    fn since(self, earlier: Self) -> Self::Duration;
    fn advance(self, duration: Self::Duration) -> Self;
    fn duration_as_f32(duration: Self::Duration) -> f32;
    fn duration_sum(
        duration: Self::Duration,
        other: Self::Duration,
    ) -> Self::Duration;
    fn duration_diff(
        duration: Self::Duration,

    ) -> Self::Duration;
    fn duration_scale(duration: Self::Duration, scale: f32) -> Self::Duration;
}

Time trait should be implemented for types that represent animation time. It’s implemented for f32, f64, std::time::Instant, and std::time::SystemTime by default. You can implement it for your own types.

Required Associated Types

type Duration: Default + PartialEq + PartialOrd + Clone + Copy

Positive time difference

Required Methods

fn since(self, earlier: Self) -> Self::Duration

Panics if self < earlier

fn advance(self, duration: Self::Duration) -> Self

fn duration_as_f32(duration: Self::Duration) -> f32

fn duration_sum( duration: Self::Duration, other: Self::Duration, ) -> Self::Duration

fn duration_diff( duration: Self::Duration, other: Self::Duration, ) -> Self::Duration

fn duration_scale(duration: Self::Duration, scale: f32) -> Self::Duration

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.
