std::_Tuple_impl< _Idx, _Elements >(3) Library Functions Manual NAME std::_Tuple_impl< _Idx, _Elements > SYNOPSIS Detailed Description template struct std::_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.
