It is based on SuperEasyJSON inspired by msgpack.
It can simply convert a vector or a map to Json Value.
using test_map_t = unordered_map<string, vector<string>>;
test_map_t map;
map["v1"] = v1;
map["v2"] = v2;
map["v3"] = v3;
Value mapValue = Convert(map);
cout << Serialize(mapValue) << endl;
test_map_t new_map;
As<test_map_t>(mapValue, new_map); //adaptor macro
class B
{
public:
B() {};
string s;
int i;
bool b;
double d;
public:
HIJSON_DEFINE(s, i, b, d)
};
