how use template <typename T> struct adl_serializer

[wuvalue]

template
struct adl_serializer {
static void to_json(json& j, const T& value) {
// calls the "to_json" method in T's namespace
}

static void from_json(const json& j, T& value) {
    // same thing, but with the "from_json" method
}

};

In order to asses your issue, we need the following information:

• What is the issue you have?

• Please describe the steps to reproduce the issue. Can you provide a small but working code example?

• What is the expected behavior?

• And what is the actual behavior instead?

• Which compiler and operating system are you using? Is it a supported compiler?

• Did you use a released version of the library or the version from the develop branch?

• If you experience a compilation error: can you compile and run the unit tests?

You specialize adl_serializer in nlohmann namespase for your types. Example is here https://github.com/nlohmann/json/blob/develop/README.md#arbitrary-types-conversions.
