Qt for Python (PySide/Shiboken)

Hi! Is it possible in shiboken6 to create a binding for a function? Here is C++ representation: using room_factory_t = std::function<Room*(Connection*, const QString&, JoinState)>; After defining std::function in namespace-type I got such error: Cannot find type entry for "Quotient::Room *(Quotient::Connection *, const QString &, Quotient::JoinState)".
