How to convert ObjectPath to std::string?

[ttmms]

Why is ObjectPath a separate object, but createProxy takes object path argument as std::string and doesn't accept ObjectPath? How do I do conversions in between?

    class ObjectPath : public std::string
    {
    public:
      ...

As you can see it is already string you don't need to convert.

        ObjectPath(std::string path)
            : std::string(std::move(path))
        {}

As you can see there is no explicit constructor for string. it can allowed to make implicit conversion.

@ttmms Originally, since object path is a string, the APIs were designed with std::string representation for object paths, interface names, bus names, etc. ObjectPath type was introduced in the sdbus-c++ type system to represent object paths as values inside D-Bus messages, to get all the automatic serialization, D-Bus signature etc. by sdbus-c++. There already was an idea of representing both concepts with one type -- ObjectPath, but was not deemed too important and was not addressed yet.
