template<typename _Key, typename _Value, typename _Alloc, typename _ExtractKey, typename _Equal, typename _Hash, typename _RangeHash, typename _Unused, typename _RehashPolicy, typename _Traits, bool _Unique_keys = _Traits::__unique_keys::value>¶

struct std::__detail::_Equality< _Key, _Value, _Alloc, _ExtractKey, _Equal, _Hash, _RangeHash, _Unused, _RehashPolicy, _Traits, _Unique_keys >" Primary class template _Equality.
