Data.Hashable — hashing keys for hash tables

Synopsis

hashMod : Int

combineHash : Int -> Int -> Int

Mix two digests (the classic 31-multiplier, à la Java hashCode), kept in [0, hashMod). Order-sensitive, so combineHash a b ≠ combineHash b a.

interface Hashable a where
hash : a -> Int

Types whose values can be hashed to an Int in [0, hashMod).
