Struct SingleVlanSlice

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

Slice containing a VLAN header & payload.

Implementations

impl<'a> SingleVlanSlice<'a>

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

Try creating a SingleVlanSlice from a slice containing the VLAN header & payload.

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

Returns the slice containing the VLAN header and payload.

pub fn priority_code_point(&self) -> VlanPcp

Read the “priority_code_point” field of the VLAN header.

This is a 3 bit number which refers to the IEEE 802.1p class of service and maps to the frame priority level.

pub fn drop_eligible_indicator(&self) -> bool

Read the “drop_eligible_indicator” flag of the VLAN header.

Indicates that the frame may be dropped under the presence of congestion.

pub fn vlan_identifier(&self) -> VlanId

Reads the 12 bits “vlan identifier” field from the VLAN header.

pub fn ether_type(&self) -> EtherType

Read the “Tag protocol identifier” field from the VLAN header.

Refer to the “EtherType” for a list of possible supported values.

pub fn to_header(&self) -> SingleVlanHeader

Decode all the fields and copy the results to a SingleVlanHeader struct

pub fn header_slice(&self) -> &[u8]

Slice containing the Ethernet 2 header.

pub fn payload(&self) -> EtherPayloadSlice<'a>

Returns the slice containing the VLAN payload & ether type identifying it’s content type.

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

Returns the slice containing the VLAN payload.

pub const fn header_len(&self) -> usize

Length of the VLAN header in bytes (equal to crate::SingleVlanHeader::LEN).

Trait Implementations

impl<'a> Clone for SingleVlanSlice<'a>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SingleVlanSlice<'_>

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

Formats the value using the given formatter.

impl<'a> PartialEq for SingleVlanSlice<'a>

fn eq(&self, other: &SingleVlanSlice<'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.
