prettier-plugin-rust VS prettyplease

Same code formatted by Prettier Rust

There are alternatives to rustfmt: Prettier Rust and genemichaels

If you're open to using an alternative, here's how Prettier Rust would format your snippet:

Nice blog, another very useful crate to use when working with proc-macro is https://github.com/dtolnay/prettyplease, for formatting generated code (very useful for debugging!), that does not bails out like rustfmt sometimes does.

I doubt you would want to actually use this human-consumed code, but an interesting alternative that I know of is David Tolnay's prettyplease. It tries to be lightweight and consistent for auto-generated code.

btw there is also https://github.com/dtolnay/prettyplease

This, I also have a bunch of files that seem to break rustfmt. Ime, it doesn't exactly refuse to format the whole file but it's picky in what and to what degree it chooses to format, basically anything flying in the complex blocks. I have run into prettyplease but I'm yet to actually try it on these offenders.

prettyplease

Optionally, format the generated code to make it more readable. You can run rustfmt on the output file, or use prettyplease before writing the file.
