Generate fusion :: vector from mpl :: vector

Question

How to generate fusion::vectorfrom mpl::vector? How to generate mpl::vectorfrom fusion::vector?

BOOST_MPL_ASSERT((is_same<
                  fusion::vector<int, char>,
                  generate_fusion_vector<mpl::vector<int, char> >::type >));

BOOST_MPL_ASSERT((is_same<
                  mpl::vector<int, char>,
                  generate_mpl_vector<fusion::vector<int, char> >::type >));

I need metafiles generate_fusion_vectorand generate_mpl_vector. I can write my own metafiles, but I suspect that they already exist.

I had experience generating fusion::mapwith help result_of::as_mapbefore, but in the current effort (trunk, 1.39), this error also occurs:

D:\Libraries\boost_trunk\boost/fusion/sequence/intrinsic/size.hpp(56) : error C2903: 'apply' : symbol is neither a class template nor a function template
        D:\Libraries\boost_trunk\boost/fusion/container/vector/convert.hpp(23) : see reference to class template instantiation 'boost::fusion::result_of::size' being compiled
        with
        [
            Sequence=boost::mpl::vector
        ]
        temp.cpp(71) : see reference to class template instantiation 'boost::fusion::result_of::as_vector' being compiled

I do not understand what's going on?

Answer 1

Since fusion accepts mpl types as arguments to functions, you can try the following:

BOOST_MPL_ASSERT((is_same<
fusion::vector<int, char>,
fusion::result_of::as_vector<mpl::vector<int, char> >::type >));

Edit:
