Struct pnet_packet::ethernet::EthernetPacket

pub struct EthernetPacket<'p> { /* fields omitted */ }

A structure enabling manipulation of on the wire packets

Implementations

impl<'a> EthernetPacket<'a>

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

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

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

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

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

Maps from a EthernetPacket to a EthernetPacket

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

Maps from a EthernetPacket to a EthernetPacket 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: &Ethernet) -> usize

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

pub fn get_destination(&self) -> MacAddr

Get the value of the destination field

pub fn get_source(&self) -> MacAddr

Get the value of the source field

pub fn get_ethertype(&self) -> EtherType

Get the value of the ethertype field
