11  * \note This header and its content are not part of the Mbed TLS API and
12  * applications must not depend on it. Its main purpose is to define the
13  * multi-part state objects of the PSA drivers included in the cryptographic
14  * library. The definitions of these objects are then used by crypto_struct.h
15  * to define the implementation-defined types of PSA multi-part state objects.
