Struct RoutingPacket

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

A structure enabling manipulation of on the wire packets

Implementations

impl<'a> RoutingPacket<'a>

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

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

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

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

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

Maps from a RoutingPacket to a RoutingPacket

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

Maps from a RoutingPacket to a RoutingPacket 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: &Routing) -> usize

The size (in bytes) of a Routing 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.

pub fn get_routing_type(&self) -> u8

Get the routing_type field.

pub fn get_segments_left(&self) -> u8

Get the segments_left field.

Trait Implementations

impl<'p> Debug for RoutingPacket<'p>

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

Formats the value using the given formatter.

impl<'p> FromPacket for RoutingPacket<'p>

type T = Routing

The type of the packet to convert from.

fn from_packet(&self) -> Routing

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

impl<'a> Packet for RoutingPacket<'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 RoutingPacket<'a>

fn packet_size(&self) -> usize

Get the calculated size of the packet.

impl<'p> PartialEq for RoutingPacket<'p>

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