🚀 The feature, motivation and pitch

• The PyTorch codebase is huge. Formatting and linting the repo takes a lot of time. Additionally, adding new linters is a bit of challenge. https://github.com/charliermarsh/ruff is a Rust linter/fixer that implements rules for the most common of flake8 linters (pyupgrade, flake8, isort, popular flake8-plugins etc). Many of our existing linters can be combined here. The only downside is that it does reduce the number of flake8-plugins we can use (since they are all reimplemented in the framework), but it does many of the autofixes. Even if we don't replace flake8 etc with this plugin, we can use it supplement it, by using it only for other modules like pyupgrade (where you can select individual pyupgrade rules etc.). I've been using to implement various PRs and it's pretty reasonable so far. See Consider upgrade to Python 3.8+ syntax with pyupgrade #94040

Alternatives

Keep the existing linters

Additional context

It's also really, really fast!
