Classes
struct	EigenHasher
	STL-compatible hasher for dense Eigen types (matrices, vectors, arrays). More...
struct	GenericHasher
	STL-compatible hasher for custom classes where you list the members to be hashed as template parameters. More...

Functions
uint64_t	murmur64 (const ByteBufferView &buffer) noexcept
	Computes the non-cryptographic 64-bit MurmurHash2 on the input data.
uint64_t	djb2 (const ByteBufferView &data) noexcept
	Computes the djb2 hash value of the input data.
template<typename T>
uint64_t	combineHash (uint64_t seed, const T &object) noexcept
	Computes the hash of object using std::hash<T> and combines it with an already existing 64bit hash.
template<>
uint64_t	combineHash (uint64_t seed, const uint64_t &hashToAdd) noexcept
	Combines existing 64bit hashes.
template<typename... Ts>
uint64_t	genericHash (const Ts &... objects) noexcept
	Convenience function to compute the combined hash of an arbitrary number of inputs.
