rusty_expressions 0.2.0

Oniguruma remade in pure Rust: named groups, look-around, backreferences, subexp calls, absent expressions, callouts, per-regex encodings (UTF-8/16/32, Shift_JIS, Big5, EUC-*, GB18030, ISO-8859-*) and Perl/Python/Java/POSIX/GNU/Emacs/grep syntax dialects. Match-equivalent to Oniguruma 6.9.10 and ~3x faster than libonig. no_std + alloc with default-features = false, runs on wasm32, no C toolchain.
