About 3ms. A manual implementation might be a bit faster, but not by much. The regex crate is quite optimized for pretty much these problems.

Wow, that is very fast, nice. I was happy with 120ms, seems I’m leaving a lot of performance on the table.
Edit: Regex cut my total time in half, but I am measuring the whole execution, still a massive improvement.

The 3ms are for part 1 only, part 2 takes around 27ms. But I see that our approaches there are very similar. One difference that might make an impact is that you copy the substrings for inserting into the hashmap into Strings.
