Struct etherparse::SingleVlanHeaderSlice

pub struct SingleVlanHeaderSlice<'a> { /* fields omitted */ }

A slice containing a single vlan header of a network package.

Methods

impl<'a> SingleVlanHeaderSlice<'a>

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

Creates a vlan header slice from a slice.

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

Returns the slice containing the single vlan header

pub fn priority_code_point(&self) -> u8

Read the "priority_code_point" field from the slice. 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 from the slice. Indicates that the frame may be dropped under the presence of congestion.

pub fn vlan_identifier(&self) -> u16

Reads the 12 bits "vland identifier" field from the slice.

pub fn ether_type(&self) -> u16

Read the "Tag protocol identifier" field from the slice. 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
