# QairtInfo Note Some methods in this module are not yet implemented in the current release and will raise an exception if called. See the C API for full functionality. **Include:** `#include "QairtCppApi/QairtInfo.hpp"` C++ wrapper for the QAIRT info API. A Backend must be created before constructing an Info object.
