Description

Type class and primitives for constructing 32 bit hashes using the MurmurHash2 algorithm. See http://murmurhash.googlepages.com for details on MurmurHash2.

Synopsis

Documentation

data Hash32 Source

A 32 bit hash.

asWord32 :: Hash32 -> Word32Source

Extract 32 bit word from hash.

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.
