Methods

impl<'a> MutableGrePacket<'a>

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

Constructs a new MutableGrePacket. 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 MutableGrePacket 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
