Enum etherparse::icmpv6::DestUnreachableCode

pub enum DestUnreachableCode {
    NoRoute,
    Prohibited,
    BeyondScope,
    Address,
    Port,
    SourceAddressFailedPolicy,
    RejectRoute,
}

“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

No route to destination

Prohibited

Communication with destination administratively prohibited

BeyondScope

Beyond scope of source address

Address

Address unreachable

Port

Port unreachable

SourceAddressFailedPolicy

Source address failed ingress/egress policy

RejectRoute

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.
