Apart from the aspect that you're new to a language and just want to learn something you might make an improved version. ripgrep is a Rust version of grep. It's the fastest grep I know and it has better Unicode support than GNU grep (because of Rust language decisions).

There are whole classes of bugs that are excluded in Rust which still pop up every once in a while in some of our basic system tools.
