It does work. The tradeoff is: * run ruff command many times (with different input file each time) * write all the files to "disk" (tempfs actually so it doesn't involve disk access) and run ruff once Currently with black I avoid that by importing it as a module once so I get the benefits of both (and is simple to boot). In other comments here I've read that a person heavily involved in Python-Rust interop is also part of the team, so there's hope they'll expose ruff as a module too and magically whisk my dilemma away :-)
