What's the best way to serialize to json a class method?

[johnsturgeon]

Let's say I have for example this class:

class Team {
public:
    std::string team_name;
    int rushing_yards;
    int passing_yards;
// rushing + passing yards
    int total_yards();
};

How can I represent that as:

{ "team_name": "Panthers", "rushing_yards": 100, "passing_yards": 50, "total_yards": 150 }

See https://json.nlohmann.me/features/arbitrary_types/ - you need to define a to_json function in the same namespace of your class. The macros do not work as they would not be able to serialize total_yards.

OMG, I got stuck when the compiler told me that const wouldn't work there, but of course the method should be marked as const...

Thanks
