Struct pnet_packet::ipv4::Ipv4OptionPacket

pub struct Ipv4OptionPacket<'p> { /* fields omitted */ }

A structure enabling manipulation of on the wire packets

Implementations

impl<'a> Ipv4OptionPacket<'a>

pub fn new<'p>(packet: &'p [u8]) -> Option<Ipv4OptionPacket<'p>>

Constructs a new Ipv4OptionPacket. If the provided buffer is less than the minimum required packet size, this will return None.

pub fn owned(packet: Vec<u8>) -> Option<Ipv4OptionPacket<'static>>

Constructs a new Ipv4OptionPacket. If the provided buffer is less than the minimum required packet size, this will return None. With this constructor the Ipv4OptionPacket will own its own data and the underlying buffer will be dropped when the Ipv4OptionPacket is.

pub fn to_immutable<'p>(&'p self) -> Ipv4OptionPacket<'p>

Maps from a Ipv4OptionPacket to a Ipv4OptionPacket

pub fn consume_to_immutable(self) -> Ipv4OptionPacket<'a>

Maps from a Ipv4OptionPacket to a Ipv4OptionPacket 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: &Ipv4Option) -> usize

The size (in bytes) of a Ipv4Option instance when converted into a byte-array

pub fn get_copied(&self) -> u1

Get the copied field.

pub fn get_class(&self) -> u2

Get the class field.

pub fn get_number(&self) -> Ipv4OptionNumber

Get the value of the number field

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

Get the raw &u8 value of the length field, without copying

pub fn get_length(&self) -> Vec<u8>

Get the value of the length field (copies contents)
