As this is a regex->DFA implementation I wonder how it compares to Google RE2 [1]

there are nice performance comparisons to glibc, rust regex and cl-ppcre, but re2 was missing from that list.

If the benchmarks are to be believed, I think it substantially outperforms re2, because it also beats Hyperscan, and I think Hyperscan typically beats re2.

re2 has limited functionality. It’s works wel for specific patterns, like crawling, but not general purpose
