Struct SLLPacket

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

A structure enabling manipulation of on the wire packets

Implementations

impl<'a> SLLPacket<'a>

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

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

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

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

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

Maps from a SLLPacket to a SLLPacket

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

Maps from a SLLPacket to a SLLPacket 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: &SLL) -> usize

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

pub fn get_packet_type(&self) -> u16be

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

pub fn get_link_layer_address_type(&self) -> u16be

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

pub fn get_link_layer_address_len(&self) -> u16be

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

pub fn get_link_layer_address_raw(&self) -> &[u8]

Get the raw &u8 value of the link_layer_address field, without copying

pub fn get_link_layer_address(&self) -> Vec<u8>

Get the value of the link_layer_address field (copies contents)

pub fn get_protocol(&self) -> EtherType

Get the value of the protocol field

Trait Implementations

impl<'p> Debug for SLLPacket<'p>

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

Formats the value using the given formatter.

impl<'p> FromPacket for SLLPacket<'p>

type T = SLL

The type of the packet to convert from.

fn from_packet(&self) -> SLL

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

impl<'a> Packet for SLLPacket<'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 SLLPacket<'a>

fn packet_size(&self) -> usize

Get the calculated size of the packet.

impl<'p> PartialEq for SLLPacket<'p>

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