Provides common access to IPv4 header fields.

Ipv4Header provides access to IPv4 header fields as a common implementation for both Ipv4Packet and Ipv4PacketRaw.

Required Methods

fn get_header_prefix(&self) -> &HeaderPrefix

Gets a reference to the IPv4 HeaderPrefix.

Provided Methods

fn dscp_and_ecn(&self) -> DscpAndEcn

The Differentiated Services Code Point (DSCP) and the Explicit Congestion Notification (ECN).

fn id(&self) -> u16

The identification.

fn df_flag(&self) -> bool

The Don’t Fragment (DF) flag.

fn mf_flag(&self) -> bool

The More Fragments (MF) flag.

fn fragment_offset(&self) -> FragmentOffset

The fragment offset.

fn fragment_type(&self) -> Ipv4FragmentType

The fragment type.

p.fragment_type() returns Ipv4FragmentType::InitialFragment if p.fragment_offset() == 0 and Ipv4FragmentType::NonInitialFragment otherwise.

fn ttl(&self) -> u8

The Time To Live (TTL).

fn proto(&self) -> Ipv4Proto

The IP Protocol.

proto returns the Ipv4Proto from the protocol field.

fn src_ip(&self) -> Ipv4Addr

The source IP address.

fn dst_ip(&self) -> Ipv4Addr

The destination IP address.

fn builder(&self) -> Ipv4PacketBuilder

Construct a builder with the same contents as this header.
