Type Alias esp_idf_sys::psa_mac_operation_t

pub type psa_mac_operation_t = psa_mac_operation_s;

The type of the state data structure for multipart MAC operations.

Before calling any function on a MAC operation object, the application must initialize it by any of the following means:

• Set the structure to all-bits-zero, for example: \code psa_mac_operation_t operation; memset(&operation, 0, sizeof(operation)); \endcode
• Initialize the structure to logical zero values, for example: \code psa_mac_operation_t operation = {0}; \endcode
• Initialize the structure to the initializer #PSA_MAC_OPERATION_INIT, for example: \code psa_mac_operation_t operation = PSA_MAC_OPERATION_INIT; \endcode
• Assign the result of the function psa_mac_operation_init() to the structure, for example: \code psa_mac_operation_t operation; operation = psa_mac_operation_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.

Aliased Type

    pub private_id: u32,
    pub private_mac_size: u8,
    pub _bitfield_align_1: [u8; 0],

}

Fields

private_id: u32

Unique ID indicating which driver got assigned to do the operation. Since driver contexts are driver-specific, swapping drivers halfway through the operation is not supported. ID values are auto-generated in psa_driver_wrappers.h ID value zero means the context is not valid or not assigned to any driver (i.e. none of the driver contexts are active).
