}

A trait for time instants that follow the API of std::time::Instant. This is useful for code that should work with not just the real time, but also simulated time.

Required Associated Types

type Duration: Duration

Required Methods

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

See std::time::Instant::duration_since.

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

See std::time::Instant::saturating_duration_since.

fn checked_duration_since(&self, earlier: Self) -> Option<Self::Duration>

See std::time::Instant::checked_duration_since.

fn checked_add(&self, duration: Self::Duration) -> Option<Self>

See std::time::Instant::checked_add.

fn checked_sub(&self, duration: Self::Duration) -> Option<Self>

See std::time::Instant::checked_sub.

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.
