This crate provides even faster functions for printing integers with default format
than [itoa](https://crates.io/crates/itoa) crate.
## Comparison with `itoa` crate
If you want to write integers in decimal format to `String`, `Vec` or any other
contiguous buffer, then this crate is the best choice.
If you want to write integers to a `std::io::Write` or `std::fmt::Write`,
[itoa](https://github.com/dtolnay/itoa) crate and `itoap` crate shows almost same
performance, but `itoap` outputs slightly larger binary.
The implementation is based on the `sse2` algorithm from
[itoa-benchmark](https://github.com/miloyip/itoa-benchmark) repository.
While `itoa` crate writes integers from **last** digits, this algorithm writes
from **first** digits. It allows integers to be written directly to the buffer.
That's why `itoap` is faster than `itoa`.
