30 * This header file is for interface Cython with C++.
31 * It should not contains any backend specific headers (like SYCL or math
32 * library) because all included headers will be exposed in Cython compilation
33 * procedure
34 *
35 * We would like to avoid backend specific things in higher level Cython
36 * modules. Any backend interface functions and types should be defined here.
37 *
38 * Also, this file should contains documentation on functions and types
39 * which are used in the interface
