Struct Stopwatch 

pub struct Stopwatch { /* private fields */ }

An open-ended count-up. Tick it with the frame delta and read Stopwatch::elapsed. Use it where there is no fixed deadline, such as time since the player last moved or how long an input has been held.

Implementations

impl Stopwatch

pub fn new() -> Stopwatch

A stopwatch at zero.

pub fn tick(&mut self, delta: f32) -> &mut Stopwatch

Advances the stopwatch by delta seconds, returning it for chaining. A paused stopwatch ignores the delta.

pub fn elapsed(&self) -> f32

Seconds accumulated since the last reset.

pub fn paused(&self) -> bool

Whether the stopwatch is paused.

pub fn set_elapsed(&mut self, elapsed: f32)

Sets the accumulated time.

pub fn set_paused(&mut self, paused: bool)

Pauses or resumes ticking.

pub fn pause(&mut self)

Pauses ticking.

pub fn unpause(&mut self)

Resumes ticking.

pub fn reset(&mut self)

Clears the accumulated time.
