Struct netsim_embed::udp::MutableUdpPacket

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

A structure enabling manipulation of on the wire packets

Implementations

impl<'a> MutableUdpPacket<'a>

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

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

pub fn owned(packet: Vec<u8, Global>) -> Option<MutableUdpPacket<'static>>

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

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

Maps from a #name to a #imm_name

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

Maps from a #name to a #imm_name 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: &Udp) -> usize

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

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

Populates a {name}Packet using a {name} structure

pub fn get_source(&self) -> u16

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

pub fn get_destination(&self) -> u16

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

pub fn get_length(&self) -> u16

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

pub fn get_checksum(&self) -> u16

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

pub fn get_payload(&self) -> Vec<u8, Global>

Get the value of the {name} field (copies contents)

pub fn set_source(&mut self, val: u16)

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

pub fn set_destination(&mut self, val: u16)

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

pub fn set_length(&mut self, val: u16)

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

pub fn set_checksum(&mut self, val: u16)

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

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

Set the value of the {name} field (copies contents)
