Struct MacsecHeaderSlice

pub struct MacsecHeaderSlice<'a> { /* private fields */ }

Slice containing a MACsec header & next ether type (if possible).

Implementations

impl<'a> MacsecHeaderSlice<'a>

pub fn from_slice( slice: &'a [u8], ) -> Result<MacsecHeaderSlice<'a>, HeaderSliceError>

Try creating a MacsecHeaderSlice from a slice containing the MACsec header & next ether type.

pub fn slice(&self) -> &'a [u8]

Slice containing the header & ether type of the next segment if available.

pub fn tci_an_raw(&self) -> u8

Raw first byte of the mac sec header (containing TCI & AN).

pub fn endstation_id(&self) -> bool

End station identifier (TCI.ES flag).

pub fn tci_scb(&self) -> bool

Ethernet passive optical network broadcast flag.

pub fn encrypted(&self) -> bool

Encryption flag, which indicates whether the user data is encrypted (true = encrypted, TCI.E flag).

pub fn userdata_changed(&self) -> bool

Flag for change text, set if the user data is modified.

pub fn is_unmodified(&self) -> bool

True if the payload was neither flagged as modified or encrypted.

pub fn ptype(&self) -> MacsecPType

Payload type (contains encryption, modification flag as well as the next ether type if available)

pub fn an(&self) -> MacsecAn

Association number (identifies SAs).

pub fn short_len(&self) -> MacsecShortLen

Short length with reserved bits.

pub fn packet_nr(&self) -> u32

Packet number.

pub fn sci_present(&self) -> bool

True if the SCI bit is set in the TCI part of the SecTag header.

pub fn sci(&self) -> Option<u64>

Secure channel identifier.

pub fn next_ether_type(&self) -> Option<EtherType>

Ether type of the data following the sec tag (only available if not encrypted and userdata is not flagged as modified).

pub fn header_len(&self) -> usize

Length of the MACsec header (SecTag + next ether type if available).

pub fn expected_payload_len(&self) -> Option<usize>

Returns the required length of the payload (data after header + next_ether_type if present) if possible.

If the length cannot be determined (short_len is zero or less then 2 when ptype Unmodified) None is returned.

pub fn to_header(&self) -> MacsecHeader

Decodes all MacSecHeader values and returns them as a crate::MacsecHeader.

Trait Implementations

impl<'a> Clone for MacsecHeaderSlice<'a>

fn clone(&self) -> MacsecHeaderSlice<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for MacsecHeaderSlice<'a>

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

Formats the value using the given formatter.

impl<'a> PartialEq for MacsecHeaderSlice<'a>

fn eq(&self, other: &MacsecHeaderSlice<'a>) -> bool

Tests for self and other values to be equal, and is used by ==.

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

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