QxJson::json_convertible Concept Reference

Specifies that a type is generally convertible to/from JSON. More...

Concept definition

template<typename T>
concept QxJson::json_convertible =  requires(T& tValue) {
    { Converter<T>::fromJson(tValue, QJsonValue()) } -> std::same_as<Qx::JsonError>;
    { Converter<T>::toJson(tValue) } -> qjson_type;
}

Detailed Description

Satisfied if a Converter specialization exists for T that includes functions with the signatures:

• static Qx::JsonError fromJson(T& value, const QJsonValue& jValue)
• static R toJson(const T& value)

where R is any type that satisfies the qjson_type concept.
