Struct etherparse::SingleVlanHeader

pub struct SingleVlanHeader {
    pub priority_code_point: u8,
    pub drop_eligible_indicator: bool,
    pub vlan_identifier: u16,
    pub ether_type: u16,
}

IEEE 802.1Q VLAN Tagging Header

Fields

priority_code_point: u8

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

drop_eligible_indicator: bool

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

vlan_identifier: u16

12 bits vland identifier.

ether_type: u16

“Tag protocol identifier”: Type id of content after this header. Refer to the “EtherType” for a list of possible supported values.

Implementations

impl SingleVlanHeader

pub fn read_from_slice(
    slice: &[u8]
) -> Result<(SingleVlanHeader, &[u8]), ReadError>

👎 Deprecated since 0.10.1:

Use SingleVlanHeader::from_slice instead.

Read an SingleVlanHeader from a slice and return the header & unused parts of the slice.

pub fn from_slice(slice: &[u8]) -> Result<(SingleVlanHeader, &[u8]), ReadError>

Read an SingleVlanHeader from a slice and return the header & unused parts of the slice.

pub fn from_bytes(bytes: [u8; 4]) -> SingleVlanHeader

Read an SingleVlanHeader from a static sized byte array.

pub fn read<T: Read + Seek + Sized>(
    reader: &mut T
) -> Result<SingleVlanHeader, Error>

Read a IEEE 802.1Q VLAN tagging header

pub fn write<T: Write + Sized>(&self, writer: &mut T) -> Result<(), WriteError>

Write the IEEE 802.1Q VLAN tagging header

pub fn header_len(&self) -> usize

Length of the serialized header in bytes.

pub fn to_bytes(&self) -> Result<[u8; 4], ValueError>

Returns the serialized form of the header or an value error in case the header values are outside of range.
