Sometimes Rust Analyzer stops formatting my VS Code document and there is no message or explanation why.
This is just one ugly example - lines 46-53 are all over the place.
No matter how many times I press Ctrl+Shift+I the IDE would not fix the formatting or tell me what's wrong.
Turns out there is a simple way to find out why Rust Analyzer fails to format the document: cargo fmt. It will tell you exactly what's broken.
In this case it was a comment on line 44 that got in the way. The document started formatting again as soon as I removed it.
Beware,
cargo fmtwill attempt to reformat the entire project. Read more about it in https://github.com/rust-lang/rustfmt or runcargo fmt -- --helpfor options.
I went back to several other files that were not formatting properly, ran cargo fmt on them and quickly fixed the problems. Happy coding!

For anyone who is using vs code and has this issue:
Look for
trailing spacesextension. It will highlight all trailing spaces in red and has a feature to quickly delete them all.it was useful for me. thanks
Thank you for figuring this out 🙏
