hash32AddWord32 :: Word32 -> Hash32 -> Hash32Source
hash32AddInt :: Int -> Hash32 -> Hash32Source
hash32 :: Hashable32 a => a -> Hash32Source
Create a hash using the default seed.
hash32WithSeed :: Hashable32 a => Word32 -> a -> Hash32Source
Create a hash using a custom seed.
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.
