Struct packet_formats::icmp::IcmpDestUnreachable

#[repr(C)]
pub struct IcmpDestUnreachable { /* private fields */ }

An ICMP Destination Unreachable message.

Implementations

impl IcmpDestUnreachable

pub fn new_for_frag_req(mtu: NonZeroU16) -> Self

Create a new ICMP Destination Unreachable message for a message with Code = Fragmentation Required (4) which requires a next hop MTU value as defined in RFC 1191 section 4.

pub fn next_hop_mtu(&self) -> Option<NonZeroU16>

Get the Next Hop MTU value as defined in RFC 1191 section 4.

Note, this field is considered unused in all Destination Unreachable ICMP messages, except for ICMPv4 Destination Unreachable messages with Code = Fragmentation Required (4).
