Struct MutableIpv4OptionPacket

pub struct MutableIpv4OptionPacket<'p> { /* private fields */ }

A structure enabling manipulation of on the wire packets

Implementations

impl<'a> MutableIpv4OptionPacket<'a>

pub fn new<'p>(packet: &'p mut [u8]) -> Option<MutableIpv4OptionPacket<'p>>

Constructs a new MutableIpv4OptionPacket. If the provided buffer is less than the minimum required packet size, this will return None.

pub fn owned(packet: Vec<u8>) -> Option<MutableIpv4OptionPacket<'static>>

Constructs a new MutableIpv4OptionPacket. If the provided buffer is less than the minimum required packet size, this will return None. With this constructor the MutableIpv4OptionPacket will own its own data and the underlying buffer will be dropped when the MutableIpv4OptionPacket is.

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

Maps from a MutableIpv4OptionPacket to a Ipv4OptionPacket

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

Maps from a MutableIpv4OptionPacket 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 populate(&mut self, packet: &Ipv4Option)

Populates a Ipv4OptionPacket using a Ipv4Option structure

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) -> Ipv4OptionType

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)

pub fn set_copied(&mut self, val: u1)

Set the copied field.

pub fn set_class(&mut self, val: u2)

Set the class field.

pub fn set_number(&mut self, val: Ipv4OptionType)

Set the value of the number field.

pub fn get_length_raw_mut(&mut self) -> &mut [u8]

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

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

Set the value of the length field (copies contents)

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

Set the value of the data field (copies contents)

Trait Implementations

impl<'p> Debug for MutableIpv4OptionPacket<'p>

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

Formats the value using the given formatter.

impl<'p> FromPacket for MutableIpv4OptionPacket<'p>

type T = Ipv4Option

The type of the packet to convert from.

fn from_packet(&self) -> Ipv4Option

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

impl<'a> MutablePacket for MutableIpv4OptionPacket<'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 MutableIpv4OptionPacket<'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 MutableIpv4OptionPacket<'a>

fn packet_size(&self) -> usize

Get the calculated size of the packet.

impl<'p> PartialEq for MutableIpv4OptionPacket<'p>

fn eq(&self, other: &MutableIpv4OptionPacket<'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.
