rustfmt binary doesn't seem to do anything on my machine

[punowo]

Hello.

I've added the binary downloaded from github to my path. I've tried both gnu and msvc. If I point it at a .rs file it won't format it. I'm confused and I'm not sure how to debug this further. I'm on Windows 10. I do not have Rust tooling installed. I just want to use rustfmt to format some rust files.

Unfortunately you'll need to have a rust toolchain installed in order to run rustfmt, and the recommended way to get rustfmt is via rustup. You'll find some additional details in #5805 (comment) and the other linked issues.
