If you have read-only mappings that you want to … Webphf HashMap uses a somewhat slow hash algorithm (quoting the documentation) to avoid DoS attacks. With large enough maps there's also a possibility of collisions. On the other hand, phf uses perfect hashing (hashing that guarantees no collisions) to build compile-time maps. This way we can have efficient constant-time lookups at runtime. the standard inn pub
