Struct Stopwatch

pub struct Stopwatch { /* private fields */ }

A simple stopwatch for measuring elapsed time.

The stopwatch starts automatically upon creation.

Examples

use khora_core::utils::timer::Stopwatch;
use std::thread;
use std::time::Duration;

let watch = Stopwatch::new();
thread::sleep(Duration::from_millis(50));
let elapsed_ms = watch.elapsed_ms().unwrap_or(0);

assert!(elapsed_ms >= 50);
