This might be relevant here: there is a Rust implementation of this algorithm by BurntSushi [1], and discussion [2] about the performances and Hyperscan [3] in the case of Suricata [4]. HyperScan being regular expression matching library using AMD64 SIMD instructions by Intel. HyperScan is in low maintenance mode, but there is a maintained fork which is compatible with more architectures: Vectorscan [5]
