Struct UdpMut

pub struct UdpMut {
    pub upper_layer: Option<Box<LayerMut>>,
    /* private fields */
}

Mutable representation of an UPD packet

Fields

upper_layer: Option<Box<LayerMut>>

the upper layer

Trait Implementations

impl Clone for UdpMut

fn clone(&self) -> UdpMut

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for UdpMut

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

Formats the value using the given formatter.

impl Display for UdpMut

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

Formats the value using the given formatter.

impl<'a> LayerMutable<'a> for UdpMut

type PacketMut = MutableUdpPacket<'a>

Mutable packet type of the pnet lib

fn new() -> Self

Creates a new mut layer instance

fn modify(&'a mut self) -> Option<Self::PacketMut>

This returns the a mutable reference to the pnet type to modify properties of the packet. If you want to modify the payload YOU must use set_payload from the LayerMutable trait

fn set_payload(&'a mut self, payload: &[u8])

Modifies the payload of the packet

fn switch_src_dst(&mut self)

If the layer contains a src and a dest this will be switch and propagated to the last layer. When called on an Eth/Ipv4/Udp this will switch the mac, ipv and the port numbers

fn add(&mut self, layer: LayerMut) -> bool

Add upper layer as payload. Returns false if it fails e.g layer is not allowed as payload If already a upper layer is defined this will be propagated to this upper layer

fn get_layer(&'a mut self, layer: &Layers) -> Option<&'a mut LayerMut>

Returns a mutable reference to the requested layer

fn from_buf(buf: Vec<u8>) -> Option<Self>

Creates a new mut layer instance base on the provided buffer

fn build(self) -> Option<Vec<u8>>

This returns the builded packet as bytes ready to send on the wire. The following will be modified: - Required packet structure information will be set to there default value if not already set - Payload types will be set - Checksum will be calculated
