Struct netsim_embed::ipv6::MutableFragmentPacket

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

A structure enabling manipulation of on the wire packets

Implementations

impl<'a> MutableFragmentPacket<'a>

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

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

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

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

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

Maps from a MutableFragmentPacket to a FragmentPacket

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

Maps from a MutableFragmentPacket to a FragmentPacket 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: &Fragment) -> usize

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

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

Populates a FragmentPacket using a Fragment structure

pub fn get_next_header(&self) -> IpNextHeaderProtocol

Get the value of the next_header field

pub fn get_reserved(&self) -> u8

Get the reserved field.

pub fn get_fragment_offset_with_flags(&self) -> u16

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

pub fn get_id(&self) -> u32

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

pub fn set_next_header(&mut self, val: IpNextHeaderProtocol)

Set the value of the next_header field.

pub fn set_reserved(&mut self, val: u8)

Set the reserved field.

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

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

pub fn set_id(&mut self, val: u32)

Set the id 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 payload field (copies contents)

impl<'p> MutableFragmentPacket<'p>

pub fn get_fragment_offset(&self) -> u16

pub fn is_last_fragment(&self) -> bool

pub fn set_fragment_offset(&mut self, offset: u16)

pub fn set_last_fragment(&mut self, is_last: bool)
