Yes, as I said, the APIs exposed in regex-automata give a lot more power. It's an "expert" level crate. You could pretty easily build a scanner-like abstraction and get pretty close to the Python code. I posted this because a lot of regex engines don't support this type of use case. Or don't support it well without having to give something up.
