Struct Timer 

pub struct Timer { /* private fields */ }

A simple countdown timer.

Useful for cooldowns, delays, and timed events.

Example

let mut timer = Timer::from_seconds(2.0, false);
// In update loop:
if timer.tick(delta) {
    println!("2 seconds elapsed!");
}

Implementations

impl Timer

pub fn from_seconds(seconds: f64, repeating: bool) -> Self

Create a timer with the given duration.

pub fn tick(&mut self, delta: f64) -> bool

Advance the timer by delta seconds. Returns true when it fires.

pub fn reset(&mut self)

Reset the timer to zero.

pub fn set_duration(&mut self, seconds: f64)

Set a new duration and reset.

pub fn fraction(&self) -> f32

Fraction completed (0.0 to 1.0).

pub fn is_finished(&self) -> bool

Whether the timer has finished (non-repeating only).

pub fn is_running(&self) -> bool

Whether the timer is still running.

pub fn remaining(&self) -> f64

Remaining time in seconds.

Trait Implementations

fn clone(&self) -> Timer

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Timer

fn fmt(&self, f: &mut Formatter<'_>) -> Result
