Bad offset: range 0..558 offset 564 in cursor.rs #146

Closed ebadta81 closed 1 year ago

Hi,

I run into this error message when trying to add tailwindcss to my leptos project, according to this comment.

Is there a missing boundary check in cursor.rs?

Can you reliably trigger this crash? Anyway, you should probably file it against the rust-analyzer repo, it's not necessarily a rowan issue.

unfortunately not. After VS restart, I don't have the error.

If you remember where you were typing (I'm assuming it was in a macro call or something with a macro attribute), feel free to open an issue in the other repo.
