Fix clippy never_loop

[hecatia-elegua]

just a small fix / refactor since clippy errored out
also passes cargo fmt now

edit: I just realized clippy has more complaints, but I'll just keep the PR this way and go on with my actual problem

[lnicola]

I take it rustfmt does the same thing? We should probably keep the comment.

Instead of turning this into a closure we can just remove the loop keyword and make use of the now stable label_break_value feature instead

[HKalbasi]

It hits rust-lang/rustfmt#5676 but we can #[rustfmt::skip] that block, or just do nothing until that issue becomes resolved.

[hecatia-elegua]

The problem was that clippy errors on this. Also it's kinda more readable, though if the closure is less performant or sth I understand

[Veykril]

Using label_break_value seems more readable to me than a closure that is called immedaitely, closures usually imply being lazy to me when used in such a way (or emulating a try block).

[HKalbasi]

@hecatia-elegua clippy is not considered a problem in this repository, but for maximizing readability I think you can make it a standalone function or method which is more readable than a labeled block and closure.
