/**
* The type of the state data structure for interruptible key generation
* operations.
*
* Before calling any function on an interruptible key generation object, the
* application must initialize it by any of the following means:
* - Set the structure to all-bits-zero, for example:
* \code
* psa_export_public_key_iop_t operation;
* memset(&operation, 0, sizeof(operation));
* \endcode
* - Initialize the structure to logical zero values, for example:
* \code
* static psa_export_public_key_iop_t operation;
* \endcode
* - Initialize the structure to the initializer #PSA_EXPORT_PUBLIC_KEY_IOP_INIT,
* for example:
* \code
* psa_export_public_key_iop_t operation = PSA_EXPORT_PUBLIC_KEY_IOP_INIT;
* \endcode
* - Assign the result of the function psa_generate_key_iop_init() to the
* structure, for example:
* \code
* psa_export_public_key_iop_t operation;
* operation = psa_export_public_key_iop_init();
* \endcode
*
* This is an implementation-defined \c struct. Applications should not
* make any assumptions about the content of this structure.
* Implementation details can change in future versions without notice.
