-
template<typename TValueType, typename TSfinae = void>
struct libsemigroups::EqualTo¶ Adapter for testing equality.
Defined in
adapters.hpp
.This type should be a stateless trivially default constructible with a call operator of signature
bool operator()(TValueType const&, TValueType const&)
(possiblynoexcept
,inline
and/orconstexpr
also) for use with, for example, std::unordered_map.- Template Parameters
TValueType – the type of objects to compare.
TSfinae – this template parameter can be used for SFINAE.
