Struct pnet::packet::gre::GrePacket
[−]
[src]
pub struct GrePacket<'p> { // some fields omitted }
A structure enabling manipulation of on the wire packets
Methods
impl<'a> GrePacket<'a>
[src]
fn new<'p>(packet: &'p [u8]) -> Option<GrePacket<'p>>
Constructs a new GrePacket. If the provided buffer is less than the minimum required packet size, this will return None.
fn to_immutable<'p>(&'p self) -> GrePacket<'p>
Maps from a GrePacket to a GrePacket
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.
fn packet_size(_packet: &Gre) -> usize
The size (in bytes) of a Gre instance when converted into a byte-array
fn get_checksum_present(&self) -> u1
Get the checksum_present field
fn get_routing_present(&self) -> u1
Get the routing_present field
fn get_key_present(&self) -> u1
Get the key_present field
fn get_sequence_present(&self) -> u1
Get the sequence_present field
