Enum packet_formats::ipv6::ext_hdrs::ExtensionHeaderOptionAction

pub enum ExtensionHeaderOptionAction {
    SkipAndContinue,
    DiscardPacket,
    DiscardPacketSendIcmp,
    DiscardPacketSendIcmpNoMulticast,
}

Action to take when an unrecognized option type is encountered.

ExtensionHeaderOptionAction is an action that MUST be taken (according to RFC 8200 section 4.2) when an IPv6 processing node does not recognize an option’s type.

Variants

SkipAndContinue

Skip over the option and continue processing the header. value = 0.

DiscardPacket

Just discard the packet. value = 1.

DiscardPacketSendIcmp

Discard the packet and, regardless of whether or not the packet’s destination address was a multicast address, send an ICMP parameter problem, code 2 (unrecognized option), message to the packet’s source address, pointing to the unrecognized type. value = 2.

DiscardPacketSendIcmpNoMulticast

Discard the packet and, and only if the packet’s destination address was not a multicast address, send an ICMP parameter problem, code 2 (unrecognized option), message to the packet’s source address, pointing to the unrecognized type. value = 3.

Trait Implementations

impl Clone for ExtensionHeaderOptionAction

fn clone(&self) -> ExtensionHeaderOptionAction

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ExtensionHeaderOptionAction

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

Formats the value using the given formatter.

impl From<ExtensionHeaderOptionAction> for u8

fn from(a: ExtensionHeaderOptionAction) -> u8

Converts to this type from the input type.

impl PartialEq for ExtensionHeaderOptionAction

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl TryFrom<u8> for ExtensionHeaderOptionAction

type Error = ()

The type returned in the event of a conversion error.

fn try_from(value: u8) -> Result<Self, ()>

Performs the conversion.
