Enum etherparse::icmpv6::DestUnreachableCode

pub enum DestUnreachableCode {
    NoRoute = 0,
    Prohibited = 1,
    BeyondScope = 2,
    Address = 3,
    Port = 4,
    SourceAddressFailedPolicy = 5,
    RejectRoute = 6,
}

“Destination Unreachable” ICMPv6 code containing a reason why a destination could not be reached.

RFC 4443 Description:

A Destination Unreachable message SHOULD be generated by a router, or by the IPv6 layer in the originating node, in response to a packet that cannot be delivered to its destination address for reasons other than congestion. (An ICMPv6 message MUST NOT be generated if a packet is dropped due to congestion.)

Variants

NoRoute = 0

No route to destination

Prohibited = 1

Communication with destination administratively prohibited

BeyondScope = 2

Beyond scope of source address

Address = 3

Address unreachable

Port = 4

Port unreachable

SourceAddressFailedPolicy = 5

Source address failed ingress/egress policy

RejectRoute = 6

Reject route to destination

Implementations

impl DestUnreachableCode

pub fn from_u8(code_u8: u8) -> Option<DestUnreachableCode>

Converts the u8 code value from an ICMPv6 “destination unreachable” packet to an icmpv6::DestUnreachableCode enum.

Example Usage:

use etherparse::{icmpv6, icmpv6::DestUnreachableCode};
let icmp_packet: [u8;8] = [
    icmpv6::TYPE_DST_UNREACH, icmpv6::CODE_DST_UNREACH_PORT, 0, 0,
    0, 0, 0, 0,
];

if icmpv6::TYPE_DST_UNREACH == icmp_packet[0] {
    let dst = icmpv6::DestUnreachableCode::from_u8(
        icmp_packet[1]
    );
    assert_eq!(dst, Some(icmpv6::DestUnreachableCode::Port));
}

pub fn code_u8(&self) -> u8

Returns the code value of the destination unreachable packet.

This is the second byte of an ICMPv6 packet.

Trait Implementations

impl Clone for DestUnreachableCode

fn clone(&self) -> DestUnreachableCode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DestUnreachableCode

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

Formats the value using the given formatter.

impl PartialEq for DestUnreachableCode

fn eq(&self, other: &DestUnreachableCode) -> 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.
