Struct FragmentPacket

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

A structure enabling manipulation of on the wire packets

Implementations

impl<'a> FragmentPacket<'a>

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

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

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

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

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

Maps from a FragmentPacket to a FragmentPacket

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

Maps from a FragmentPacket to a FragmentPacket 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: &Fragment) -> usize

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

pub fn get_next_header(&self) -> IpNextLevelProtocol

Get the value of the next_header field

pub fn get_reserved(&self) -> u8

Get the reserved field.

pub fn get_fragment_offset_with_flags(&self) -> u16be

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

pub fn get_id(&self) -> u32be

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

impl<'p> FragmentPacket<'p>

pub fn get_fragment_offset(&self) -> u16

pub fn is_last_fragment(&self) -> bool

Trait Implementations

impl<'p> Debug for FragmentPacket<'p>

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

Formats the value using the given formatter.

impl<'p> FromPacket for FragmentPacket<'p>

type T = Fragment

The type of the packet to convert from.

fn from_packet(&self) -> Fragment

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

impl<'a> Packet for FragmentPacket<'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 FragmentPacket<'a>

fn packet_size(&self) -> usize

Get the calculated size of the packet.

impl<'p> PartialEq for FragmentPacket<'p>

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