Yeah, the implementation is literally just a token-by-token transliteration into Rust, just hoping that LLVM makes it go fast (and it does go pretty fast, e.g. it's faster than bff4[1], which Esolangs[2] touts as the fastest interpreter). The Rust output & optimised IR clearly show there's room for improvement, though.
