Thanks @whizsid! Note CI is failing and we're blocked on https://github.com/rust-lang/rust/issues/78549

[calebcartwright]

Blocking issues should be resolved. When you get a chance can you rebase on master to grab the latest and get CI passing?

Thanks for the updates! This PR has been sitting out here for a while though, would you please rebase on master?

While there's a few nits I do think the approach seems reasonable, and the resulting formatting is certainly better than what it exists today (some of these snippets get horribly butchered today).

I'd like to add a couple more test cases before merging though, just to be extra cautious. Could you add a couple snippets to cover the following:

• A trailing mix of a block comment followed by a line comment (use foo; /* bar */ // evil
• Multiline block comments
• imports within indented scopes (e.g inside an inline module, function, etc.)

After those tests are added, should be good to merge
