Struct ieee802154::mac::frame::security::AuxiliarySecurityHeader

pub struct AuxiliarySecurityHeader {
    pub control: SecurityControl,
    pub key_identifier: Option<KeyIdentifier>,
    /* private fields */
}

A struct describing the Auxiliary Security Header

See: section 7.4

Fields

control: SecurityControl

The control field in the Auxiliary Security Header

key_identifier: Option<KeyIdentifier>

If the key_identifier field in AuxiliarySecurityHeader::control is not set to None, this field contains the key identifier of this frame, otherwise it is None

Implementations

impl AuxiliarySecurityHeader

pub fn get_octet_size(&self) -> usize

Get the size of this security header, in octets

pub fn new(
    control: SecurityControl,
    key_identifier: Option<KeyIdentifier>
) -> Self

Create a new Auxiliary Security Header with the specified control and key identifier

pub unsafe fn new_unsafe(
    control: SecurityControl,
    key_identifier: Option<KeyIdentifier>,
    frame_counter: u32
) -> Self

Create a new Auxiliary Security Header with the specified control, key identifier, and frame counter.

This function is unsafe because the frame_counter is almost always set when parsing a frame from a buffer, or by the security context at the time of actually writing a secured frame.

pub fn get_frame_counter(&self) -> u32

Get the frame counter of this auxiliary security header.

This will be 0 on a non-parsed Auxiliary Security Header

Trait Implementations

impl Clone for AuxiliarySecurityHeader

fn clone(&self) -> AuxiliarySecurityHeader

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AuxiliarySecurityHeader

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for AuxiliarySecurityHeader

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given Hasher.

impl PartialEq<AuxiliarySecurityHeader> for AuxiliarySecurityHeader

fn eq(&self, other: &AuxiliarySecurityHeader) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryRead<'_, ()> for AuxiliarySecurityHeader

fn try_read(bytes: &[u8], _ctx: ()) -> Result<(Self, usize)>

Try to read from bytes using context.

impl<AEADBLKCIPH, KEYDESCLO> TryWrite<&SecurityContext<AEADBLKCIPH, KEYDESCLO>> for AuxiliarySecurityHeader where
    AEADBLKCIPH: NewBlockCipher + BlockCipher<BlockSize = U16>,
    KEYDESCLO: KeyDescriptorLookup<AEADBLKCIPH::KeySize>, 

fn try_write(
    self,
    bytes: &mut [u8],
    sec_ctx: &SecurityContext<AEADBLKCIPH, KEYDESCLO>
) -> Result<usize>

Try to write to bytes using context.
