This crate provides a fast conversion of integer primitives to decimal strings.
The implementation comes straight from [libcore] but avoids the performance
penalty of going through [`core::fmt::Formatter`].

See also [`ryu`] for printing floating point primitives.

*Version requirement: rustc 1.36+*

[libcore]: https://github.com/rust-lang/rust/blob/b8214dc6c6fc20d0a660fb5700dca9ebf51ebe89/src/libcore/fmt/num.rs#L201-L254
[`core::fmt::Formatter`]: https://doc.rust-lang.org/std/fmt/struct.Formatter.html
[`ryu`]: https://github.com/dtolnay/ryu

```toml
[dependencies]
itoa = "1.0"
```


## Example

```rust
fn main() {
    let mut buffer = itoa::Buffer::new();
    let printed = buffer.format(128u64);
    assert_eq!(printed, "128");
}
```


## Performance (lower is better)
