Struct pnet::packet::gre::GrePacket
[−]
[src]
pub struct GrePacket<'p> { /* 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 owned(packet: Vec<u8>) -> Option<GrePacket<'static>>
Constructs a new GrePacket. If the provided buffer is less than the minimum required packet size, this will return None. With this constructor the GrePacket will own its own data and the underlying buffer will be dropped when the GrePacket is.
fn to_immutable<'p>(&'p self) -> GrePacket<'p>
Maps from a GrePacket to a GrePacket
fn consume_to_immutable(self) -> GrePacket<'a>
Maps from a GrePacket to a GrePacket while consuming the source
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_sequence_raw(&self) -> &[u8]
Get the raw &[u8] value of the sequence field, without copying
fn get_sequence(&self) -> Vec<U32BE>
