What would it take to add refinement types to Rust?

    For what it's worth, with the uom[0] crate you can represent that type equality. It represents units as powers of SI units, so m^1s^-2. It does not have the nice error messages though

      Having refinement types in Rust would be a massive game changer. It would make it possible to write proven correct software directly in Rust. Hey even I would switch from C++ to Rust :)
