Struct FakeClock 

pub struct FakeClock { /* private fields */ }

A fake clock for testing time-dependent code

Allows manual control of time progression, enabling fast and deterministic tests for Debouncer, Throttler, etc.

Example

use egui_cha::testing::FakeClock;
use egui_cha::helpers::Debouncer;
use std::time::Duration;

let clock = FakeClock::new();
let mut debouncer = Debouncer::with_clock(clock.clone());

debouncer.trigger(Duration::from_millis(500), Msg::Search);

// Time hasn't passed yet
assert!(!debouncer.should_fire());

// Advance time past the debounce delay
clock.advance(Duration::from_millis(600));
assert!(debouncer.should_fire());

Implementations

impl FakeClock

pub fn new() -> Self

Create a new fake clock starting at time zero

pub fn advance(&self, duration: Duration)

Advance the clock by the specified duration

pub fn set(&self, time: Duration)

Set the clock to a specific time

pub fn get(&self) -> Duration

Get the current time

pub fn reset(&self)

Reset the clock to time zero

Trait Implementations

impl Clone for FakeClock

fn clone(&self) -> FakeClock

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Default for FakeClock

fn default() -> Self

Returns the “default value” for a type.
