Usually we try to make match statements exhaustive in order to catch errors when new variants are added.

I'd keep this the old way too. It's good to see all the options listed.

The same here and constness above. It's a bit more verbose to list all variants, but also a lot more readable for someone who does not know the code base by heart.

A few cleanups for hir - prefer `if let` to `match` when only 1 branch matters - `chain` iterable items that are looped over in sequence - `sort_by_key` instead of `sort_by` when possible - change cloning `map`s to `cloned()` - use `unwrap_or_else` and `ok` when applicable - a few other minor readability improvements - whitespace fixes
