Struct IcmpPacketRaw

pub struct IcmpPacketRaw<I: IcmpIpExt, B: SplitByteSlice, M: IcmpMessage<I>> { /* private fields */ }

A partially parsed and not yet validated ICMP packet.

An IcmpPacketRaw provides minimal parsing of an ICMP packet. Namely, it only requires that the header and message (in ICMPv6, these are both considered part of the header) are present, and that the header has the expected message type. The body may be missing (or an unexpected body may be present). Other than the message type, no header, message, or body field values will be validated.

IcmpPacket provides a [FromRaw] implementation that can be used to validate an IcmpPacketRaw.

Implementations
