BOOST_FUSION_ADAPT_TPL_STRUCT is a macro that can be used to generate all the necessary boilerplate to make an arbitrary template struct a model of Random Access Sequence.

    (struct_name) (specialization_param0)(specialization_param1)...,
    (member_type0, member_name0)
    (member_type1, member_name1)

The above macro generates the necessary code to adapt struct_name or an arbitrary specialization of struct_name as a model of Random Access Sequence. The sequence (template_param0)(template_param1)... declares the names of the template type parameters used. The sequence (specialization_param0)(specialization_param1)... declares the template parameters of the actual specialization of struct_name that is adapted as a fusion sequence. The sequence of (member_typeN, member_nameN) pairs declares the type and names of each of the struct members that are part of the sequence.

The macro should be used at global scope, and struct_name should be the fully namespace qualified name of the struct to be adapted.

#include <boost/fusion/adapted/struct/adapt_struct.hpp>
#include <boost/fusion/include/adapt_struct.hpp>
namespace demo
    template<typename Name, typename Age>
    struct employee
        Name name;
        Age age;

// Any instantiated demo::employee is now a Fusion sequence
    (demo::employee) (Name)(Age),
    (Name, name)
    (Age, age))
