Enum NetHeaders 

pub enum NetHeaders {
    Ipv4(Ipv4Header, Ipv4Extensions),
    Ipv6(Ipv6Header, Ipv6Extensions),
    Arp(ArpPacket),
}

Headers on the network layer (e.g. IP, ARP, …).

Variants

Ipv4(Ipv4Header, Ipv4Extensions)

IPv4 header & extension headers.

Ipv6(Ipv6Header, Ipv6Extensions)

IPv6 header & extension headers.

Arp(ArpPacket)

Address Resolution Protocol packet.

Implementations

impl NetHeaders

pub fn is_ip(&self) -> bool

Returns true if the NetHeaders contains either IPv4 or IPv6.

pub fn is_ipv4(&self) -> bool

Returns true if the NetHeaders contains IPv4.

pub fn is_ipv6(&self) -> bool

Returns true if the NetHeaders contains IPv6.

pub fn is_arp(&self) -> bool

Returns true if the NetHeaders contains ARP.

pub fn ipv4_ref(&self) -> Option<(&Ipv4Header, &Ipv4Extensions)>

Returns references to the IPv4 header & extensions if the header contains IPv4 values.

pub fn ipv6_ref(&self) -> Option<(&Ipv6Header, &Ipv6Extensions)>

Returns references to the IPv6 header & extensions if the header contains IPv6 values.

pub fn arp_ref(&self) -> Option<&ArpPacket>

Returns references to the ARP packet if the header contains ARP values.

pub fn try_set_next_headers( &mut self, last_next_header: IpNumber, ) -> Result<EtherType, NetSetNextHeaderError>

Sets all the next_header fields in the ipv4 & ipv6 header as well as in all extension headers and returns the ether type number.

The given number will be set as the last “next_header” or protocol number.

pub fn header_len(&self) -> usize

Returns the size when the header & extension headers are serialized

Trait Implementations

impl Clone for NetHeaders

fn clone(&self) -> NetHeaders

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NetHeaders

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

Formats the value using the given formatter.

impl From<ArpPacket> for NetHeaders

fn from(value: ArpPacket) -> Self

Converts to this type from the input type.

impl From<IpHeaders> for NetHeaders

fn from(value: IpHeaders) -> Self

Converts to this type from the input type.

impl PartialEq for NetHeaders

fn eq(&self, other: &NetHeaders) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
