There is nothing Rust specific as far as I’m aware, other than the developers are comfortable with the language. They have a very fast dependency resolver/algo, but presumably you could implement that in C or Zig or whatever. It is much faster than if it was implemented in Python or another interpreted language though. Ruff is way, way faster than the equivalent Python tools. I like Rust for the type safety and tooling so that may slow them to build faster?
