Welcome to itoap 👋

This crate provides even faster functions for printing integers with default format than 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 crate and itoap crate shows almost same performance, but itoap outputs slightly larger binary.

The implementation is based on the branchlut algorithm from 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.
