Enum IpPacket 

pub enum IpPacket<'a> {
    V4(Ipv4Packet<'a>),
    V6(Ipv6Packet<'a>),
}

Available on crate feature net only.

A checked IP packet, independent of its link or tunnel protocol.

Variants

V4(Ipv4Packet<'a>)

IPv4 packet.

V6(Ipv6Packet<'a>)

IPv6 packet.

Implementations

impl<'a> IpPacket<'a>

pub fn parse(bytes: &'a [u8]) -> Result<IpPacket<'a>, IpPacketError>

Parse one packet; Self::as_bytes excludes trailing link-layer padding.

pub fn as_bytes(self) -> &'a [u8]

Complete packet bytes.

pub fn encode_forwarded( self, output: impl BufMut, ) -> Result<usize, IpPacketError>

Append this validated packet and decrement its hop count. The IPv4 checksum is updated incrementally (RFC 1624); options need no reparse. An exhausted hop count or short output leaves the output untouched.

pub fn source(self) -> IpAddr

Source address.

pub fn destination(self) -> IpAddr

Destination address.

pub fn protocol(self) -> Option<IpProtocol>

Upper-layer protocol, if available without reassembly.

pub fn upper_layer_payload(self) -> Option<&'a [u8]>

Upper-layer bytes, absent for non-initial fragments and No Next Header.

pub fn hop_limit(self) -> u8

TTL / Hop Limit.

pub fn traffic_class(self) -> u8

DSCP and ECN bits.

pub fn ecn(self) -> EcnCodepoint

Explicit Congestion Notification codepoint.

pub fn fragment(self) -> Option<IpFragment>

Fragment metadata; IPv4 has identification even when not fragmented.

Trait Implementations

impl<'a> Clone for IpPacket<'a>

fn clone(&self) -> IpPacket<'a>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Copy for IpPacket<'a>

impl<'a> Debug for IpPacket<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.
