Voxell's Timers

let data = time_eprintln!{hello mom, generate_data() };
// -> hello mom: 309ms

This library provides a simple way to time code execution. Simply use the provided macros/functions to time your code to get a Duration and the result of the block/closure.

Example 1

use voxell_timer::*;

let (result, time) = time! {
    for _ in 0..1_000_000 {
        let _ = std::hint::black_box(3);
    }
    10
};
eprintln!("Took {}ms", time.as_millis());
assert_eq!(result, 10);

Example 2

use voxell_timer::*;

let haystack = vec![1, 2, 3, 4, 5, 6];
let result = time_println! {
    "Finding needle in haystack",
    let needle = 4;
    haystack.iter().find(|a| **a == needle)
};

assert_eq!(result, Some(&4));

Example 3

use voxell_timer::*;

let haystack = vec![1, 2, 3, 4, 5, 6];
let result = time_fn_println("Finding needle in haystack", || {
    let needle = 4;
    haystack.iter().find(|a| **a == needle)
});
assert_eq!(result, Some(&4));
