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.
[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
# Example
```
fn main() {
let mut buffer = itoa::Buffer::new();
let printed = buffer.format(128u64);
assert_eq!(printed, "128");
}
```
# Performance (lower is better)
