Struct ArpReader

pub struct ArpReader<'a> {
    pub bytes: &'a [u8],
}

Reads ARP header fields.

Fields

bytes: &'a [u8]

Implementations

impl<'a> ArpReader<'a>

pub fn new(bytes: &'a [u8]) -> Result<Self, &'static str>

Creates a new ArpReader from the given slice.

pub fn htype(&self) -> u16

Returns the hardware type field.

Specifies the type of hardware used for the network (e.g. Ethernet).

pub fn ptype(&self) -> u16

Returns the protocol type field.

Specifies the type of protocol address (e.g. IPv4).

pub fn hlen(&self) -> u8

Returns the hardware length field.

Specifies the length of the hardware address in bytes.

pub fn plen(&self) -> u8

Returns the protocol length field.

Specifies the length of the protocol address in bytes.

pub fn oper(&self) -> u16

Returns the operation field.

Specifies the operation being performed (e.g. request, reply).

pub fn sha(&self) -> &[u8]

Returns the sender hardware address field.

Specifies the hardware address of the sender.

pub fn spa(&self) -> &[u8]

Returns the sender protocol address field.

Specifies the protocol address of the sender.

pub fn tha(&self) -> &[u8]

Returns the target hardware address field.

Specifies the hardware address of the receiver

pub fn tpa(&self) -> &[u8]

Returns the target protocol address field.

Specifies the protocol address of the receiver.

pub fn header_len(&self) -> usize

Returns the header length in bytes.

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

Returns a reference to the header.

pub fn payload(&self) -> &[u8]

Returns a reference to the payload.

Trait Implementations

impl Debug for ArpReader<'_>

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

Formats the value using the given formatter.

impl<'a> ParseReader<'a> for ArpReader<'a>

fn parse(bytes: &'a [u8]) -> Result<Self, &'static str>

Parses an ARP packet from a byte slice.

Validates the ARP operation field.

impl<'a> PartialEq for ArpReader<'a>

fn eq(&self, other: &ArpReader<'a>) -> 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.
