Struct pnet_packet::vlan::MutableVlanPacket

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

A structure enabling manipulation of on the wire packets

Implementations

impl<'a> MutableVlanPacket<'a>

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

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

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

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

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

Maps from a MutableVlanPacket to a VlanPacket

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

Maps from a MutableVlanPacket to a VlanPacket 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: &Vlan) -> usize

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

pub fn populate(&mut self, packet: &Vlan)

Populates a VlanPacket using a Vlan structure

pub fn get_priority_code_point(&self) -> ClassOfService

Get the value of the priority_code_point field

pub fn get_drop_eligible_indicator(&self) -> u1

Get the drop_eligible_indicator field.

pub fn get_vlan_identifier(&self) -> u12be

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

pub fn get_ethertype(&self) -> EtherType

Get the value of the ethertype field

pub fn set_priority_code_point(&mut self, val: ClassOfService)

Set the value of the priority_code_point field.

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

Set the drop_eligible_indicator field.

pub fn set_vlan_identifier(&mut self, val: u12be)

Set the vlan_identifier field. This field is always stored big-endian within the struct, but this mutator wants host order.

pub fn set_ethertype(&mut self, val: EtherType)

Set the value of the ethertype field.

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

Set the value of the payload field (copies contents)
