Enum Icmpv4PacketRaw 

pub enum Icmpv4PacketRaw<B: SplitByteSlice> {
    EchoReply(IcmpPacketRaw<Ipv4, B, IcmpEchoReply>),
    DestUnreachable(IcmpPacketRaw<Ipv4, B, IcmpDestUnreachable>),
    Redirect(IcmpPacketRaw<Ipv4, B, Icmpv4Redirect>),
    EchoRequest(IcmpPacketRaw<Ipv4, B, IcmpEchoRequest>),
    TimeExceeded(IcmpPacketRaw<Ipv4, B, IcmpTimeExceeded>),
    ParameterProblem(IcmpPacketRaw<Ipv4, B, Icmpv4ParameterProblem>),
    TimestampRequest(IcmpPacketRaw<Ipv4, B, Icmpv4TimestampRequest>),
    TimestampReply(IcmpPacketRaw<Ipv4, B, Icmpv4TimestampReply>),
}

A raw ICMPv4 packet with a dynamic message type.

Unlike IcmpPacketRaw, Packet only supports ICMPv4, and does not require a static message type. Each enum variant contains an IcmpPacketRaw of the appropriate static type, making it easier to call parse without knowing the message type ahead of time while still getting the benefits of a statically-typed packet struct after parsing is complete.

impl<I: IcmpIpExt, B: SplitByteSliceMut> GenericOverIp<I> for Icmpv4PacketRaw<B>

type Type = <I as IcmpIpExt>::IcmpPacketTypeRaw<B>

The type of Self when its IP-generic parameter is replaced with the type NewIp.

impl<B: SplitByteSliceMut> IcmpPacketTypeRaw<B, Ipv4> for Icmpv4PacketRaw<B>

fn update_checksum_pseudo_header_address( &mut self, old: Ipv4Addr, new: Ipv4Addr, )

Update the checksum to reflect an updated address in the pseudo header.

fn update_checksum_header_field<F: IntoBytes + Immutable>( &mut self, old: F, new: F, )

fn message_body_mut(&mut self) -> &mut B

Returns a mutable reference to the body of this packet.

fn update_checksum_header_field_u16(&mut self, old: u16, new: u16)
