I would highly recommend not making rustfmt a hard-dependency of your crate, not every developer will have it installed, and especially not on CI systems. If you look at how bindgen handles it they just log and output the unformatted code if rustfmt is not available.

Thank you! My crate depends on tonic, and it enables rustfmt by default. I will disable it.

It might be worth opening an issue on tonic to have a fallback when rustfmt isn't available like bindgen, so that you get nicer generated code when possible.
