## Detailed Description

### template<typename _Key, typename _Value, typename _Alloc, typename _ExtractKey, typename _Equal, typename _H1, typename _H2, typename _Hash, typename _RehashPolicy, typename _Traits, bool _Unique_keys = _Traits::__unique_keys::value>
struct std::__detail::_Map_base< _Key, _Value, _Alloc, _ExtractKey, _Equal, _H1, _H2, _Hash, _RehashPolicy, _Traits, _Unique_keys >

Primary class template _Map_base.

If the hashtable has a value type of the form pair<T1, T2> and a key extraction policy (_ExtractKey) that returns the first part of the pair, the hashtable gets a mapped_type typedef. If it satisfies those criteria and also has unique keys, then it also gets an operator[].
