std::tuple

This module provides adapters for std::tuple. Including the module header makes std::tuple a fully conforming Random Access Sequence.

	Important
	To be fully conforming, compiler should support C++11 Variadic Templates.

Header

#include <boost/fusion/adapted/std_tuple.hpp>
#include <boost/fusion/include/std_tuple.hpp>

Model of

Random Access Sequence

Example

std::tuple<int, std::string, float> p(123, "Hola!!!", 456.f);
std::cout << at_c<0>(p) << std::endl;
std::cout << at_c<1>(p) << std::endl;
std::cout << p << std::endl;
