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