Struct packet_formats::ipv4::Ipv4PacketRaw

pub struct Ipv4PacketRaw<B> { /* private fields */ }

A partially parsed and not yet validated IPv4 packet.

Ipv4PacketRaw provides minimal parsing of an IPv4 packet, namely it only requires that the fixed header part (HeaderPrefix) be retrieved, all the other parts of the packet may be missing when attempting to create it.

Ipv4Packet provides a [FromRaw] implementation that can be used to validate an Ipv4PacketRaw.

Implementations

impl<B: ByteSlice> Ipv4PacketRaw<B>

pub fn body(&self) -> MaybeParsed<&[u8], &[u8]>

Return the body.

body returns [MaybeParsed::Complete] if the entire body is present (as determined by the header’s “total length” and “internet header length” fields), and [MaybeParsed::Incomplete] otherwise.
