Struct ArpPacket

pub struct ArpPacket<'p> { /* private fields */ }

A structure enabling manipulation of on the wire packets

Implementations

impl<'a> ArpPacket<'a>

pub fn new<'p>(packet: &'p [u8]) -> Option<ArpPacket<'p>>

Constructs a new ArpPacket. If the provided buffer is less than the minimum required packet size, this will return None.

pub fn owned(packet: Vec<u8>) -> Option<ArpPacket<'static>>

Constructs a new ArpPacket. If the provided buffer is less than the minimum required packet size, this will return None. With this constructor the ArpPacket will own its own data and the underlying buffer will be dropped when the ArpPacket is.

pub fn to_immutable<'p>(&'p self) -> ArpPacket<'p>

Maps from a ArpPacket to a ArpPacket

pub fn consume_to_immutable(self) -> ArpPacket<'a>

Maps from a ArpPacket to a ArpPacket while consuming the source

pub const fn minimum_packet_size() -> usize

The minimum size (in bytes) a packet of this type can be. It’s based on the total size of the fixed-size fields.

pub fn packet_size(_packet: &Arp) -> usize

The size (in bytes) of a Arp instance when converted into a byte-array

pub fn get_hardware_type(&self) -> ArpHardwareType

Get the value of the hardware_type field

pub fn get_protocol_type(&self) -> EtherType

Get the value of the protocol_type field

pub fn get_hw_addr_len(&self) -> u8

Get the hw_addr_len field.

pub fn get_proto_addr_len(&self) -> u8

Get the proto_addr_len field.

pub fn get_operation(&self) -> ArpOperation

Get the value of the operation field

pub fn get_sender_hw_addr(&self) -> MacAddr

Get the value of the sender_hw_addr field

pub fn get_sender_proto_addr(&self) -> Ipv4Addr

Get the value of the sender_proto_addr field

pub fn get_target_hw_addr(&self) -> MacAddr

Get the value of the target_hw_addr field

pub fn get_target_proto_addr(&self) -> Ipv4Addr

Get the value of the target_proto_addr field

Trait Implementations

impl<'p> Debug for ArpPacket<'p>

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

Formats the value using the given formatter.

impl<'p> FromPacket for ArpPacket<'p>

type T = Arp

The type of the packet to convert from.

fn from_packet(&self) -> Arp

Converts a wire-format packet to #[packet] struct format.

impl<'a> Packet for ArpPacket<'a>

fn packet<'p>(&'p self) -> &'p [u8]

Retrieve the underlying buffer for the packet.

fn payload<'p>(&'p self) -> &'p [u8]

Retrieve the payload for the packet.

impl<'a> PacketSize for ArpPacket<'a>

fn packet_size(&self) -> usize

Get the calculated size of the packet.

impl<'p> PartialEq for ArpPacket<'p>

fn eq(&self, other: &ArpPacket<'p>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
