There’s uutils/coreutils which just replaces all GNU Coreutils with Rust reimplemntations 🤷‍♂️ Seems risky. They do note that “some options might be missing or different behavior might be experienced”. I have a lot bash scripts that depend on stable implementations and won’t be using this one (again, they do note that “differences with GNU are treated as bugs”). Maybe one day.

fselect allows you to search your filesystem with SQL-like queries!

starship allows you to customize your bash (or other) prompts. Written in Rust and is advertized to be blazingly fast.
