 *
 * \brief PSA cryptography module: Mbed TLS structured type implementations
 *
 * \note This file may not be included directly. Applications must
 * include psa/crypto.h.
 *
 * This file contains the definitions of some data structures with
 * implementation-specific definitions.
 *
 * In implementations with isolation between the application and the
 * cryptography module, it is expected that the front-end and the back-end
 * would have different versions of this file.
 *
 * <h3>Design notes about multipart operation structures</h3>
 *
 * For multipart operations without driver delegation support, each multipart
 * operation structure contains a `psa_algorithm_t alg` field which indicates
 * which specific algorithm the structure is for. When the structure is not in
 * use, `alg` is 0. Most of the structure consists of a union which is
 * discriminated by `alg`.
 *
 * For multipart operations with driver delegation support, each multipart
 * operation structure contains an `unsigned int id` field indicating which
 * driver got assigned to do the operation. When the structure is not in use,
 * 'id' is 0. The structure contains also a driver context which is the union
 * of the contexts of all drivers able to handle the type of multipart
 * operation.
 *
 * Note that when `alg` or `id` is 0, the content of other fields is undefined.
 * In particular, it is not guaranteed that a freshly-initialized structure
 * is all-zero: we initialize structures to something like `{0, 0}`, which
 * is only guaranteed to initializes the first member of the union;
 * GCC and Clang initialize the whole structure to 0 (at the time of writing),
 * but MSVC and CompCert don't.
 *
 * In Mbed TLS, multipart operation structures live independently from
 * the key. This allows Mbed TLS to free the key objects when destroying
 * a key slot. If a multipart operation needs to remember the key after
 * the setup function returns, the operation structure needs to contain a
 * copy of the key.
