template<>
using libsemigroups::FroidurePinTraits<TElementType>::Hash = libsemigroups::Hash<element_type>

Defined in adapters.hpp.

This type should be a stateless trivially default constructible with a call operator of signature size_t operator()(TValueType const&) for use with, for example, std::unordered_map.

The second template parameter exists for SFINAE in overload resolution.
