Typedef Documentation

fallback_allocator_adaptor

template<typename primary_alloc >

using metall::utility::fallback_allocator_adaptor = typedef metall::container::fallback_allocator_adaptor<primary_alloc>

hash

template<typename T = void, unsigned int seed = 123>

using metall::utility::hash = typedef metall::mtlldetail::hash<seed>

Hash a value of type T.

Template Parameters

T	Data type to hash. If void is specified, the hash data type is determined by () operator.
seed	A seed value used for hashing.

str_hash

template<unsigned int seed = 123>

using metall::utility::str_hash = typedef metall::mtlldetail::str_hash<seed>

Hash function for std::string-compatible string container.

Template Parameters

seed	A seed value used for hashing.

rand_512

using metall::utility::rand_512 = typedef detail::base_rand_xoshiro<detail::xoshiro512pp>

pseudo-random number generator that has a similar interface as the ones in STL The actual algorithm is uses xoshiro512++ whose period is 2^(512-1)

rand_1024

using metall::utility::rand_1024 = typedef detail::base_rand_xoshiro<detail::xoshiro1024pp>

pseudo-random number generator that has a similar interface as the ones in STL The actual algorithm is uses xoshiro1024++ whose period is 2^(1024-1)
