# Timeit for Rust
This crate provides macros that make it easy to benchmark blocks of code. It is
inspired and named after [timeit](https://docs.python.org/3/library/timeit.html) from Python.
## Examples
```rust
#[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:
```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);
}
});
```
