Concept definition

template<class K, typename T, Qx::CStringLiteral N>
concept QxJson::json_override_convertible =  requires(T& tValue) {
    { MemberOverrideCoverter<K, N>::fromJson(tValue, QJsonValue()) } -> std::same_as<Qx::JsonError>;
    { MemberOverrideCoverter<K, N>::toJson(tValue) } -> qjson_type;
}

Detailed Description

Satisfied if QX_JSON_MEMBER_OVERRIDE() has been used to add functions to a JSON-tied struct with the signatures:

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

where R is any type that satisfies the qjson_type concept.
