Boost fusion sequence type and name identification for structs and class

Question

I am trying to use boost fusion for one of my projects and I an figuring out how to get type names and variable names for structures and classes.

#include &         


        

Answer 1

I distilled the answer by sehe into something much simpler, provided you are using C++14

#include 

#include 
#include 
#include 
#include 

struct MyStruct {
    std::string foo;
    double bar;
};

BOOST_FUSION_ADAPT_STRUCT(MyStruct,
                          foo,
                          bar)

namespace fuz = boost::fusion;
namespace mpl = boost::mpl;

int main(int argc, char* argv[]) {
  MyStruct dummy{"yo",3.14};

  fuz::for_each(mpl::range_c<
                unsigned, 0, fuz::result_of::size::value>(),
                [&](auto index){
      std::cout << "Name: "
                << fuz::extension::struct_member_name::call()
                << " Value: "
                << fuz::at_c(dummy) << std::endl; 
    });

}

Outputs:

Name: foo Value: yo
Name: bar Value: 3.14
