Struct ArpSlice 

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

Available on crate feature extractors only.

ARP packet slice (RFC 826).

Fixed-format 28-byte ARP for Ethernet/IPv4: 8-byte header (htype, ptype, hlen, plen, oper) + sender HA/PA + target HA/PA.

Implementations

impl<'a> ArpSlice<'a>

pub fn htype(&self) -> u16

Hardware type (Ethernet = 1).

pub fn ptype(&self) -> u16

Protocol type (IPv4 = 0x0800).

pub fn hlen(&self) -> u8

Hardware address length (6 for Ethernet).

pub fn plen(&self) -> u8

Protocol address length (4 for IPv4).

pub fn oper(&self) -> u16

Operation (1 = request, 2 = reply).

pub fn sender_ha(&self) -> Option<[u8; 6]>

Sender hardware address. Returns None if hlen ≠ 6.

pub fn sender_pa(&self) -> Option<Ipv4Addr>

Sender protocol address (assumes IPv4 — returns None if plen ≠ 4).

pub fn target_ha(&self) -> Option<[u8; 6]>

Target hardware address (assumes hlen=6).

pub fn target_pa(&self) -> Option<Ipv4Addr>

Target protocol address (assumes IPv4).

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

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

pub fn kind(&self) -> LayerKind

impl<'a> Copy for ArpSlice<'a>

impl<'a> Debug for ArpSlice<'a>

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