I'm not sure if you knew this or not, but in the last few months, the `regex` crate grew a sub-crate called `regex-syntax` which exposes a full blown, well tested, regex parser/AST tree: https://doc.rust-lang.org/regex/regex_syntax/index.html\r\n\r\nI briefly looked over yours, and it looks like it supports everything except negative matches. Not sure if that's a deal breaker, but thought I drop a note anyway!"}}
