从boost融合适应的结构中获取成员类型列表

#include <boost/fusion/include/adapt_struct.hpp>
#include <boost/fusion/include/as_vector.hpp>
#include <boost/fusion/include/vector.hpp>
#include <boost/fusion/include/at_c.hpp>
#include <boost/type_traits.hpp>

// 定义融合适应的结构
struct MyStruct {
  int member1;
  double member2;
  std::string member3;
};

// 使用BOOST_FUSION_ADAPT_STRUCT宏适应结构
BOOST_FUSION_ADAPT_STRUCT(
    MyStruct,
    (int, member1)
    (double, member2)
    (std::string, member3)
)

int main() {
  // 获取成员类型列表
  typedef boost::fusion::result_of::as_vector<MyStruct> member_types;
  member_types::type members;

  // 输出成员类型
  std::cout << boost::fusion::at_c<0>(members).type_info().name() << std::endl;
  std::cout << boost::fusion::at_c<1>(members).type_info().name() << std::endl;
  std::cout << boost::fusion::at_c<2>(members).type_info().name() << std::endl;

  return 0;
}
