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