Struct MutableExtensionPacket

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

A structure enabling manipulation of on the wire packets

Implementations

impl<'a> MutableExtensionPacket<'a>

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

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

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

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

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

Maps from a MutableExtensionPacket to a ExtensionPacket

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

Maps from a MutableExtensionPacket 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 populate(&mut self, packet: &Extension)

Populates a ExtensionPacket using a Extension structure

pub fn get_next_header(&self) -> IpNextLevelProtocol

Get the value of the next_header field

pub fn get_hdr_ext_len(&self) -> u8

Get the hdr_ext_len field.

pub fn set_next_header(&mut self, val: IpNextLevelProtocol)

Set the value of the next_header field.

pub fn set_hdr_ext_len(&mut self, val: u8)

Set the hdr_ext_len field.

pub fn set_options(&mut self, vals: &[u8])

Set the value of the options field (copies contents)

Trait Implementations

impl<'p> Debug for MutableExtensionPacket<'p>

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

Formats the value using the given formatter.

impl<'p> FromPacket for MutableExtensionPacket<'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> MutablePacket for MutableExtensionPacket<'a>

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

Retrieve the underlying, mutable, buffer for the packet.

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

Retrieve the mutable payload for the packet.

fn clone_from<T>(&mut self, other: &T)

where T: Packet,

Initialize this packet by cloning another.

impl<'a> Packet for MutableExtensionPacket<'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 MutableExtensionPacket<'a>

fn packet_size(&self) -> usize

Get the calculated size of the packet.

impl<'p> PartialEq for MutableExtensionPacket<'p>

fn eq(&self, other: &MutableExtensionPacket<'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.
