pub struct MutableGrePacket<'p> { /* fields omitted */ }A structure enabling manipulation of on the wire packets
Methods
impl<'a> MutableGrePacket<'a>[src]
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 owned(packet: Vec<u8>) -> Option<MutableGrePacket<'static>>
Constructs a new MutableGrePacket. If the provided buffer is less than the minimum required packet size, this will return None. With this constructor the MutableGrePacket will own its own data and the underlying buffer will be dropped when the MutableGrePacket is.
fn to_immutable<'p>(&'p self) -> GrePacket<'p>
Maps from a MutableGrePacket to a GrePacket
fn consume_to_immutable(self) -> GrePacket<'a>
Maps from a MutableGrePacket 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 populate(&mut self, packet: &Gre)
Populates a GrePacket using a Gre structure
