Struct FrameHeader 

pub struct FrameHeader {
    pub ether_type: u16,
    pub kind: u8,
    pub version: u8,
    pub crc: u32,
}

Frame header structure (fixed-width, 8 bytes)

Fields

ether_type: u16

EtherType identifying the protocol

kind: u8

Frame kind (see FrameKind enum)

version: u8

Protocol version

crc: u32

CRC32 checksum of payload

Implementations

impl FrameHeader

pub fn new(ether_type: u16, kind: u8, payload: &[u8]) -> Self

Create a new frame header with computed CRC from pre-encoded payload

pub fn encode_into(&self, buf: &mut [u8; 8])

Encode header directly into a pre-allocated buffer (zero-copy)

pub fn decode(buf: &[u8]) -> Option<Self>

Decode header from bytes (zero-copy, no allocation)
