Data.BloomFilter.Hash

Contents

Description

Fast hashing of Haskell values. The hash used is XXH3 64bit.

Synopsis

Basic hash functionality

A hash value is 64 bits wide.

The salt value to be used for hashes.

class Hashable a where Source #

The class of types that can be converted to a hash value.

The instances are meant to be stable, the hash values can be persisted.

Methods

Arguments

Compute a 64-bit hash of a value.
