std::tuple
From cppreference.com
| Defined in header <tuple>

| template< class... Types > class tuple; |
(since C++11) | |
Class template std::tuple is a fixed-size collection of heterogeneous values. It is a generalization of std::pair.
If std::is_trivially_destructible<Ti>::value is true for every Ti in Types, the destructor of std::tuple is trivial.
If a program declares an explicit or partial specialization of std::tuple, the program is ill-formed, no diagnostic required.
