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

```rust

[macro_use]

extern crate timeit;

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

This will output something like:

text 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:

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