Struct VlanHdr 

#[repr(C)]
pub struct VlanHdr {
    pub tci: [u8; 2],
    pub ether_type: u16,
}

VLAN tag header structure

Fields

tci: [u8; 2]

First 2 bytes containing PCP (3 bits), DEI (1 bit), and VLAN ID (12 bits)

ether_type: u16

EtherType field indicating the protocol encapsulated in the payload

Implementations

impl VlanHdr

pub const LEN: usize

pub fn pcp(&self) -> u8

Extract the Priority Code Point (PCP) from the VLAN header

pub fn dei(&self) -> u8

Extract the Drop Eligible Indicator (DEI) from the VLAN header

pub fn vid(&self) -> u16

Extract the VLAN ID from the VLAN header

pub fn ether_type(&self) -> Result<EtherType, EthernetError>

Get the EtherType value

impl<'de, WincodeConfig: Config> SchemaRead<'de, WincodeConfig> for VlanHdr

const TYPE_META: TypeMeta

Metadata about the type’s serialization.

type Dst = VlanHdr

fn read( reader: impl Reader<'de>, dst: &mut MaybeUninit<Self::Dst>, ) -> ReadResult<()>

Read into dst from reader.

impl<WincodeConfig: Config> ZeroCopy<WincodeConfig> for VlanHdr

where for<'_wincode_internal> [u8; 2]: ZeroCopy<WincodeConfig>, for<'_wincode_internal> u16: ZeroCopy<WincodeConfig>, for<'_wincode_internal> Assert<{ _ }>: IsTrue,

fn from_bytes<'de>(bytes: &'de [u8], config: C) -> Result<&'de Self, ReadError>

where Self: Sized + SchemaRead<'de, C, Dst = Self>,

Like crate::ZeroCopy::from_bytes, but allows the caller to provide a custom configuration.

fn from_bytes_mut<'de>( bytes: &'de mut [u8], config: C, ) -> Result<&'de mut Self, ReadError>

where Self: Sized + SchemaRead<'de, C, Dst = Self>,

Like crate::ZeroCopy::from_bytes_mut, but allows the caller to provide a custom configuration.
