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

Zero-copy 802.1Q VLAN tag parser.

Holds a reference to the underlying byte slice starting at the VLAN tag.

Implementations

impl<'a> VlanPacket<'a>

pub fn new(buf: &'a [u8]) -> Option<Self>

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

Raw bytes backing this tag.

pub fn pcp(&self) -> u8

Priority Code Point (3 bits).

pub fn dei(&self) -> bool
