_Tuple_impl<; _Idx, _Elements >(3cxx) _Tuple_impl< _Idx, _Elements >(3cxx)NAME_Tuple_impl< _Idx, _Elements > -SYNOPSISDetailed Description template<std::size_t _Idx, typename... _Elements>struct _Tuple_impl< _Idx, _Elements > Contains the actual implementation of the tuple template, stored as a recursive inheritance hierarchy from the first element (most derived class) to the last (least derived class). The Idx parameter gives the 0-based index of the element stored at this point in the hierarchy; we use it to implement a constant-time get() operation. Definition at line 178 of file tuple.
