NAME
std::_Tuple_impl< _Idx, _Elements > -
SYNOPSIS
Detailed Description
template<std::size_t _Idx, typename... _Elements>
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.
