The dpctl provides integration header dpctl4pybind11.hpp which implements type casters establishing mapping between dpctl.SyclQueue and sycl::queue, dpctl.SyclDevice and sycl::device, dpctl.SyclEvent and sycl::event, etc.

The header also defines C++ classes dpctl::tensor::usm_ndarray and dpctl::memory::usm_memory which derive from pybind11::object and encapsulate Python objects of types dpctl.tensor.usm_ndarray and dpctl.memory._Memory respectively.
