Struct pnet_packet::icmp::IcmpPacket

pub struct IcmpPacket<'p> { /* fields omitted */ }

A structure enabling manipulation of on the wire packets

Methods

impl<'a> IcmpPacket<'a>

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

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

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

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

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

Maps from a IcmpPacket to a IcmpPacket

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

Maps from a IcmpPacket to a IcmpPacket while consuming the source

pub 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: &Icmp) -> usize

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

pub fn get_icmp_type(&self) -> IcmpType

Get the value of the icmp_type field

pub fn get_icmp_code(&self) -> IcmpCode

Get the value of the icmp_code field

pub fn get_checksum(&self) -> u16be

Get the checksum field. This field is always stored big-endian within the struct, but this accessor returns host order.

Trait Implementations

impl<'p> PartialEq<IcmpPacket<'p>> for IcmpPacket<'p>

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

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &IcmpPacket<'p>) -> bool

This method tests for !=.
