Timeit for Rust

This crate provides macros that make it easy to benchmark blocks of code. It is inspired and named after timeit from Python.

Examples

#[macro_use]
extern crate timeit;

fn main() {
    timeit!({
        let mut x: Vec<u64> = Vec::new();
        for i in 0..1000 {
            x.push(i);
        }
    });
}

This will output something like:

10000 loops: 2.4843 µs

It will determine the number of loops automatically. To run a specified number of loops and save the elapsed time to a variable, use the timeit_loops! macro:

let sec = timeit_loops!(100, {
    let mut x: Vec<u64> = Vec::new();
    for i in 0..1000 {
        x.push(i);
    }
});
