fnv_offset_basis_v

template<class Scalar, class Dummy = nullptr_t>

Scalar std::hash_detail::fnv_offset_basis_v {0}

externconstexpr

The FNV offset basis to use depending on bit variant.

Template Parameters

Scalar	the scalar type
Dummy	a dummy type to allow partial specialization of variable template

The value of this constant depends on the bit length of the hash being used, determined by the type of Scalar. The value of this constant for common bit-lengths is provided by the paper "The FNV Non-Cryptographic Hash Algorithm".

fnv_offset_basis_v< uint32_t, Dummy >

template<class Dummy>

uint32_t std::hash_detail::fnv_offset_basis_v< uint32_t, Dummy > {2166136261UL}

constexpr

The FNV 32-bit offset basis.

Template Parameters

Dummy

a dummy type to allow partial specialization of variable template

fnv_offset_basis_v< uint64_t, Dummy >

template<class Dummy>

uint64_t std::hash_detail::fnv_offset_basis_v< uint64_t, Dummy > {14695981039346656037ULL}

constexpr

The FNV 64-bit offset basis.

Template Parameters

Dummy

a dummy type to allow partial specialization of variable template

fnv_prime_v

template<class Scalar, class Dummy = nullptr_t>

Scalar std::hash_detail::fnv_prime_v {0}

externconstexpr

The FNV prime to use depending on bit variant.

Template Parameters

Scalar	the scalar type
Dummy	a dummy type to allow partial specialization of variable template

The value of this constant depends on the bit length of the hash being used, determined by the type of Scalar. The value of this constant for common bit-lengths is provided by the paper "The FNV Non-Cryptographic Hash Algorithm".
