Struct pnet_packet::ipv6::ExtensionPacket

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

A structure enabling manipulation of on the wire packets

Implementations

impl<'a> ExtensionPacket<'a>

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

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

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

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

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

Maps from a ExtensionPacket to a ExtensionPacket

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

Maps from a ExtensionPacket to a ExtensionPacket 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: &Extension) -> usize

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

pub fn get_next_header(&self) -> IpNextHeaderProtocol

Get the value of the next_header field

pub fn get_hdr_ext_len(&self) -> u8

Get the hdr_ext_len field.

Trait Implementations

impl<'p> Debug for ExtensionPacket<'p>

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

Formats the value using the given formatter.

impl<'p> FromPacket for ExtensionPacket<'p>

type T = Extension

The type of the packet to convert from.

fn from_packet(&self) -> Extension

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

impl<'a> Packet for ExtensionPacket<'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 ExtensionPacket<'a>

fn packet_size(&self) -> usize

Get the calculated size of the packet.

impl<'p> PartialEq for ExtensionPacket<'p>

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

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

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

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