mpl sequence

This module provides adapters for MPL sequences. Including the module header makes all MPL sequences fully conforming fusion sequences.

Header
#include <boost/fusion/adapted/mpl.hpp>
#include <boost/fusion/include/mpl.hpp>
Model of
Example
mpl::vector_c<int, 123, 456> vec_c;
fusion::vector2<int, long> v(vec_c);
std::cout << at_c<0>(v) << std::endl;
std::cout << at_c<1>(v) << std::endl;

v = mpl::vector_c<int, 456, 789>();
std::cout << at_c<0>(v) << std::endl;
std::cout << at_c<1>(v) << std::endl;
Bi-directional adaptation

Fusion sequences may also be adapted as fully conforming MPL sequences (see Intrinsics). That way, we can have 2-way adaptation to and from MPL and Fusion. To make Fusion sequences fully conforming MPL sequences, include:

#include <boost/fusion/mpl.hpp>

If you want bi-directional adaptation to and from MPL and Fusion, simply include:

#include <boost/fusion/include/mpl.hpp>

The header includes all the necessary headers.
