Timing macros for Rust modelled after Python's timeit

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);
    }
});
