Struct EthHdr 

#[repr(C)]
pub struct EthHdr {
    pub dst_addr: [u8; 6],
    pub src_addr: [u8; 6],
    pub ether_type: u16,
}

Ethernet header structure that appears at the beginning of every Ethernet frame. This structure represents the standard IEEE 802.3 Ethernet header format.

Fields

dst_addr: [u8; 6]

Destination MAC address.

src_addr: [u8; 6]

Source MAC address.

ether_type: u16

Protocol which is encapsulated in the payload of the frame. Indicates what type of data follows the Ethernet header (e.g., IPv4, IPv6, ARP)

Implementations

impl EthHdr

pub const LEN: usize

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

Attempts to convert the raw ether_type field into an EtherType enum. Returns either the corresponding EtherType variant or the raw value if unknown.

Returns

• Ok(EtherType) if a known protocol type
• Err(u16) if an unknown protocol type (returns the raw value)

pub fn new(dst_addr: [u8; 6], src_addr: [u8; 6], eth_type: EtherType) -> Self

Creates a new Ethernet header with the specified addresses and protocol type

Parameters

• dst_addr: The destination MAC address
• src_addr: The source MAC address
• ether_type_enum: The protocol type encapsulated in the payload

Returns

A new EthHdr structure initialized with the given values

Trait Implementations

impl Clone for EthHdr

fn clone(&self) -> EthHdr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EthHdr

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

Formats the value using the given formatter.

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

const TYPE_META: TypeMeta

Metadata about the type’s serialization.

type Dst = EthHdr

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

Read into dst from reader.

fn get(reader: impl Reader<'de>) -> Result<Self::Dst, ReadError>

impl<WincodeConfig: Config> SchemaWrite<WincodeConfig> for EthHdr

const TYPE_META: TypeMeta

Metadata about the type’s serialization.

type Src = EthHdr

fn size_of(src: &Self::Src) -> WriteResult<usize>

Get the serialized size of Self::Src.

fn write(writer: impl Writer, src: &Self::Src) -> WriteResult<()>

Write Self::Src to writer.

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

where for<'_wincode_internal, '_wincode_internal> [u8; 6]: 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.
