Struct pnet_packet::gre::MutableU32BEPacket

pub struct MutableU32BEPacket<'p> { /* fields omitted */ }

A structure enabling manipulation of on the wire packets

Implementations

impl<'a> MutableU32BEPacket<'a>

pub fn new<'p>(packet: &'p mut [u8]) -> Option<MutableU32BEPacket<'p>>

Constructs a new MutableU32BEPacket. If the provided buffer is less than the minimum required packet size, this will return None.

pub fn owned(packet: Vec<u8>) -> Option<MutableU32BEPacket<'static>>

Constructs a new MutableU32BEPacket. If the provided buffer is less than the minimum required packet size, this will return None. With this constructor the MutableU32BEPacket will own its own data and the underlying buffer will be dropped when the MutableU32BEPacket is.

pub fn to_immutable<'p>(&'p self) -> U32BEPacket<'p>

Maps from a MutableU32BEPacket to a U32BEPacket

pub fn consume_to_immutable(self) -> U32BEPacket<'a>

Maps from a MutableU32BEPacket to a U32BEPacket 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: &U32BE) -> usize

The size (in bytes) of a U32BE instance when converted into a byte-array

pub fn populate(&mut self, packet: &U32BE)

Populates a U32BEPacket using a U32BE structure

pub fn get_number(&self) -> u32be

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

pub fn set_number(&mut self, val: u32be)

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

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

Set the value of the unused field (copies contents)
