}

An extension trait adding ICMP-related functionality to Ipv4 and Ipv6.

Required Associated Types

type IcmpMessageType: IcmpMessageType

The type of ICMP messages.

For Ipv4, this is Icmpv4MessageType, and for Ipv6, this is Icmpv6MessageType.

type ParameterProblemCode: PartialEq + Send + Sync + Debug

The type of an ICMP parameter problem code.

For Ipv4, this is Icmpv4ParameterProblemCode, and for Ipv6 this is Icmpv6ParameterProblemCode.

type ParameterProblemPointer: PartialEq + Send + Sync + Debug

The type of an ICMP parameter problem pointer.

For Ipv4, this is u8, and for Ipv6 this is u32.

type HeaderLen: PartialEq + Send + Sync + Debug

The type of an ICMP parameter header length.

For Ipv4, this is usize, and for Ipv6 this is ().

Required Associated Constants

const ICMP_IP_PROTO: <Self as IpProtoExt>::Proto

The identifier for this ICMP version.

This value will be found in an IPv4 packet’s Protocol field (for ICMPv4 packets) or an IPv6 fixed header’s or last extension header’s Next Heeader field (for ICMPv6 packets).

const ECHO_REPLY: Self::IcmpMessageType

Icmp{v4,v6}MessageType::EchoReply.

const ECHO_REQUEST: Self::IcmpMessageType

Icmp{v4,v6}MessageType::EchoRequest.

Required Methods

fn header_len(bytes: &[u8]) -> usize

Computes the length of the header of the packet prefix stored in bytes.

Given the prefix of a packet stored in bytes, compute the length of the header of that packet, or bytes.len() if bytes does not contain the entire header. If the version is IPv6, the returned length should include all extension headers.

Object Safety

This trait is not object safe.
