Added std::regex to the regex shootout at https://github.com/rust-leipzig/regex-performance . Compiled with gcc 9.3.0 on Ubuntu 20.04, AMD Ryzen Th 3960X 128MB cache. Test file 16MiB, 300k lines, 2.6m words. Times are in milliseconds per file. Benchmark does not count regex object creation/compiling, only match.

  An implementation of regular expressions for Rust. This implementation uses finite automata and guarantees linear time matching on all inputs.

  

That one rust_regex result being so much slower than everything else irked me, so I filed an for it here: https://github.com/rust-lang/regex/issues/827
