we also have a Rust implementation of the core engine, but it’s there because we want a native library without dependencies and good UTF-8 support, not because it’s necessarily faster. in fact, the F# version is faster than the Rust version - .NET has an effortless way to vectorize regexes with SearchValues<T, and our implementation is able to detect and utilize these opportunities when most other engines can’t. replicating what .NET gives you for free would take considerable effort, and i haven’t done that in Rust yet - especially since many existing SIMD subroutines only work left to right, while .NET also provides right-to-left variants needed for our bidirectional matching.
