There was a problem hiding this comment.
If we're optimizing for readability here, I'd probably write this like:
if !explained.insert(sub.as_str()) {
continue;
}There was a problem hiding this comment.
And possibly also change the as_str to call it to_string to make it clear that it returns a String.

probably call this to_string, or maybe just implement ToString

…gestion, r=compiler-errors Simplify `printf` and shell format suggestions Simplify tracking `printf` and shell format suggestions. Although allocations could be deferred until after checking that they aren't already in the map, this style is simpler.
