Enum Icmpv4Packet

pub enum Icmpv4Packet<B: SplitByteSlice> {
    EchoReply(IcmpPacket<Ipv4, B, IcmpEchoReply>),
    DestUnreachable(IcmpPacket<Ipv4, B, IcmpDestUnreachable>),
    Redirect(IcmpPacket<Ipv4, B, Icmpv4Redirect>),
    EchoRequest(IcmpPacket<Ipv4, B, IcmpEchoRequest>),
    TimeExceeded(IcmpPacket<Ipv4, B, IcmpTimeExceeded>),
    ParameterProblem(IcmpPacket<Ipv4, B, Icmpv4ParameterProblem>),
    TimestampRequest(IcmpPacket<Ipv4, B, Icmpv4TimestampRequest>),
    TimestampReply(IcmpPacket<Ipv4, B, Icmpv4TimestampReply>),
}

An ICMPv4 packet with a dynamic message type.

Unlike IcmpPacket, Packet only supports ICMPv4, and does not require a static message type. Each enum variant contains an IcmpPacket 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.
