[struct_pb][feat]to proto

[qicosmos]

Why

• improve dynamic reflection
• support struct to proto

What is changing

Example

enum Color { Red = 0, Black = 2, Green = 4 };

namespace iguana {
template <>
struct enum_value<Color> {
  constexpr static std::array<int, 3> value = {0, 2, 4};
};

struct vector_t {
  int id;
  Color color;
  std::variant<int, pair_t, std::string> variant;
  std::vector<int> ids;
  std::vector<pair_t> pairs;
  std::vector<std::string> strs;
  std::map<std::string, pair_t> map;
  std::string name;
  std::optional<int> op_val;
};
REFLECTION(vector_t, id, color, variant, ids, pairs, strs, map, name, op_val);

void test() {
    std::string str;
    iguana::to_proto<vector_t>(str, "pb");
    std::cout << str;

    std::ofstream file("test_vector.proto", std::ios::binary);
    iguana::to_proto_file<vector_t>(file, "pb");
}

syntax = "proto3";

package pb;

option optimize_for = SPEED;

option cc_enable_arenas = true;

message vector_t {
  int32 id = 1;
  Color color = 2;
  oneof variant {
    int32  one_of_int32 = 3;
    pair_t  one_of_pair_t = 4;
    string  one_of_string = 5;
  }
  repeated  int32 ids = 6;
  repeated  pair_t pairs = 7;
  repeated  string  strs = 8;
  map<string, pair_t>  map = 9;
  string  name = 10;
  int32 op_val = 11;
}

message pair_t {
  int32 x = 1;
  int32 y = 2;
}

enum Color {
  Red = 0;
