Module hash

Provides fast HashSet and HashMap implementations based on a simplified implementation of the fast Rust C hash algorithm also used by Firefox. By default, Rust’s HashMap and HashSet use a DDoS resistant but slower hashing algorithm. FxHasher is much faster (between 2x to 5x from my testing).
