Trait Implementations

impl Header for IcmpHeader

fn make(self) -> PacketData

'cook' the header, returning it as a Vec<u8>. this function will calculate checksums, even though they will be over-written by the OS if the packet is sent 'down the wire', likewise with a lot of length fields and such.

fn parse(raw_data: &[u8]) -> Result<Box<Self>, ParseError>

parse() should never be run from a box, is hould only ever br un as ::parse(). this is just here to complete the implementation of Header onto boxed structs that implement header

fn get_proto(&self) -> Protocol

fn get_length(&self) -> u8

get the current length of the header in bytes. this usually just returns a fixed value as most headers dont have variable length, only really IP does and even then its rare for it to be > 20 bytes

fn get_min_length() -> u8

get the minimum length (in bytes) that this type of header can be

fn into_transport_header(&mut self) -> Option<&mut dyn TransportHeader>

attempts to coerce the header (a type which implements the Header trait) into a &mut dyn TransportHeader. Only returns Option::Some when the underlying concrete type is a UdpHeader or a TcpHeader
