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+*
```toml
[dependencies]
itoa = "1.0"
```
<br>
## Example
```rust
fn main() {
let mut buffer = itoa::Buffer::new();
let printed = buffer.format(128u64);
assert_eq!(printed, "128");
}
```

## Performance (lower is better)
