}

The IP context providing dispatch to the available transport protocols.

This trait acts like a demux on the transport protocol for ingress IP packets.

Required Associated Types

type EarlyDemuxSocket: SocketMetadata<Self>

Early Demux result.

Required Methods

fn early_demux<B: ParseBuffer>( &mut self, device: &Self::DeviceId, frame_dst: Option<FrameDestination>, src_ip: I::Addr, dst_ip: I::Addr, proto: I::Proto, body: B, ) -> Option<Self::EarlyDemuxSocket>

Performs early demux result.

fn dispatch_receive_ip_packet<B: BufferMut, H: IpHeaderInfo<I>>( &mut self, bindings_ctx: &mut BC, device: &Self::DeviceId, src_ip: I::RecvSrcAddr, dst_ip: SpecifiedAddr<I::Addr>, proto: I::Proto, body: B, info: &LocalDeliveryPacketInfo<I, H>, early_demux_socket: Option<Self::EarlyDemuxSocket>, ) -> Result<(), I::IcmpError>

Dispatches a received incoming IP packet to the appropriate protocol. In case of a failure returns the kind of the ICMP error that should be sent back to the source.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
