Crate palex

A fast, small, dependency-free crate for lexing command-line arguments. You can use this crate if you want to build your own argument parsing library.

This crate is almost zero-cost, since it parses arguments lazily and avoids most heap allocations. There’s no dynamic dispatch.

Check the examples folder for examples.
