hash64AddWord64 :: Word64 -> Hash64 -> Hash64 Source
Add a 64 bit word to the hash.
hash64AddInt :: Int -> Hash64 -> Hash64 Source
hash64 :: Hashable64 a => a -> Hash64 Source
Create a hash using the default seed.
hash64WithSeed :: Hashable64 a => Word64 -> a -> Hash64 Source
Create a hash using a custom seed. h The seed should be non-zero, but other than that can be an arbitrary number. Different seeds will give different hashes, and thus (most likely) different hash collisions.
