Simpler Timer

This library provides a very simple, poll based timer.

To use, include the following in Cargo.toml

[dependencies]
simpler_timer = "0.2.0"

use simpler_timer::Timer;
use std::time::Duration;

fn main() {
    let periodic = Timer::with_duration(Duration::from_millis(100));
    let timeout = Timer::with_duration(Duration::from_secs(2));
    

    loop {
        if periodic.expired() {
            println!("tick");
            periodic.reset();
        }

        if timeout.expired() {
            break;
        }
    }

    println!("total elapsed time: {}ms", timeout.elapsed().as_millis());
}

lib.rs:

simpler_timer

A simple timer mechanism to track arbitrary timeouts. It doesn't do anything fancy, e.g. no callbacks upon expiry, just give it a Duration and poll if the timer is expired. Timers can be reset and reused for periodic contexts, such as a simple time based control loop.

Example

use std::time::Duration;

// 100ms timer
let tick = Timer::with_duration(Duration::from_millis(100));
// 1 sec timer
let end = Timer::with_duration(Duration::from_secs(1));

loop {
    if tick.expired() {
        // do something interesting
        println!("tick");
        tick.reset();
    }

    if end.expired() { 
        // don't reset, let's get out of here
        break; 
    }
}

println!("total time: {}ms", end.elapsed().as_millis());
