Struct netsim_embed::tcp::MutableTcpOptionPacket

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

A structure enabling manipulation of on the wire packets

Implementations

impl<'a> MutableTcpOptionPacket<'a>

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

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

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

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

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

Maps from a MutableTcpOptionPacket to a TcpOptionPacket

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

Maps from a MutableTcpOptionPacket to a TcpOptionPacket 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: &TcpOption) -> usize

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

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

Populates a TcpOptionPacket using a TcpOption structure

pub fn get_number(&self) -> TcpOptionNumber

Get the value of the number field

pub fn get_length_raw(&self) -> &[u8]

Get the raw &u8 value of the length field, without copying

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

Get the value of the length field (copies contents)

pub fn set_number(&mut self, val: TcpOptionNumber)

Set the value of the number field.

pub fn get_length_raw_mut(&mut self) -> &mut [u8]

Get the raw &mut u8 value of the length field, without copying

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

Set the value of the length field (copies contents)

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

Set the value of the data field (copies contents)
