Trait for providing time information to the animation system.

This trait abstracts time operations to support both std and no_std environments. Implementations can use system clocks, hardware timers, or external time sources.

Required Methods

fn current_time_ms(&self) -> Milliseconds

Get the current time in milliseconds since some reference point.

The reference point doesn’t matter as long as it’s consistent. This is typically used for calculating elapsed time between calls.

fn current_time_us(&self) -> Microseconds

Get the current time in microseconds since some reference point.

This provides higher precision timing for fine-grained animations. The reference point should be the same as current_time_ms().

fn last_time_ms(&self) -> Milliseconds

Get the last recorded time in milliseconds.

This is used internally by elapsed_ms().

fn last_time_us(&self) -> Microseconds

Get the last recorded time in microseconds.

This is used internally by elapsed_us().

fn update_last_time_ms(&mut self, time: Milliseconds)

Update the last recorded time in milliseconds.

This is used internally by elapsed_ms().

fn update_last_time_us(&mut self, time: Microseconds)

Update the last recorded time in microseconds.

This is used internally by elapsed_us().

Provided Methods

fn elapsed_ms(&mut self) -> Milliseconds

Calculate elapsed time in milliseconds since the last call.

This is a convenience method that handles the delta calculation. The implementation should track the last time internally.

fn elapsed_us(&mut self) -> Microseconds

Calculate elapsed time in microseconds since the last call.

This is a convenience method that handles the delta calculation. The implementation should track the last time internally.

fn reset(&mut self)

Reset the time provider to start fresh timing.

This resets any internal state and starts timing from the current moment.
