# QairtMem 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/QairtMem.hpp"` C++ wrappers for the QAIRT memory descriptor and shape APIs. Provides type-safe access to memory descriptors and shapes used to describe tensor memory for QAIRT operations.
