Allow for forward declaring nlohmann::json #381
Description
To avoid including json.hpp in header files, I would like to forward declare nlohmann::json as follows:
namespace nlohmann { struct json; }
struct my_stuff
{
int some_member;
nlohmann::json encode() const;
void decode(nlohmann::json const&);
};However, this doesn't work, since nlohmann::json is a typedef. If you just derived it from basic_json<>, it would work:
struct json : basic_json<>
{
using basic_json<>::basic_json;
};What do you think?
