rusty_expressions

1

Rust alternative to Oniguruma, ending C regex engine memory unsafety

rusty_expressions is the Remade with Rust pin for this lane: keep the product shape, change the safety floor, and stop shipping the old C or cloud default by accident.

Instant benefit

rustyexpressions is Oniguruma, remade in pure Rust: the engine behind Ruby, PHP mbereg and jq, rebuilt from its documented behaviour. Named groups, look-around, backreferences, subexp calls, atomic and possessive groups, absent expressions, conditionals, callouts, per-regex encodings and pluggable syntax dialects. No C, no FFI, no onig-sys,.
