Enum IcmpError 

#[non_exhaustive]
pub enum IcmpError {
    NetUnreachable,
    HostUnreachable,
    ProtoUnreachable,
    PortUnreachable,
    PacketTooBig,
    Other,
}

ICMP error reported against a socket.

Returned by take_icmp_error on UDP and TCP sockets (and by UdpSocket::recv) when an ICMP error message quoting one of the socket’s packets arrives. Requires the icmp-errors cargo feature.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

NetUnreachable

The destination network is unreachable (ENETUNREACH).

HostUnreachable

The destination host is unreachable (EHOSTUNREACH). Also reported when the stack’s own neighbor resolution (ARP/NDISC) for the destination fails.

ProtoUnreachable

The destination host does not speak this protocol (EPROTO).

PortUnreachable

Nothing is listening on the destination port (ECONNREFUSED).

PacketTooBig

The packet was too big for a link on the path and could not be fragmented (EMSGSIZE): ICMPv4 “fragmentation needed and DF set” / ICMPv6 packet too big.

Other

Any other error: time exceeded, parameter problem, source route failed, …
