Trait IpLayerHandler

pub trait IpLayerHandler<I: IpExt + FragmentationIpExt, BC>: DeviceIdContext<AnyDevice> {
    // Required methods
    fn send_ip_packet_from_device<S>(
        &mut self,
        bindings_ctx: &mut BC,
        meta: SendIpPacketMeta<I, &Self::DeviceId, Option<SpecifiedAddr<I::Addr>>>,
        body: S,
    ) -> Result<(), IpSendFrameError<S>>
       where S: TransportPacketSerializer<I>,
             S::Buffer: BufferMut;
    fn send_ip_frame<S>(
        &mut self,
        bindings_ctx: &mut BC,
        device: &Self::DeviceId,
        destination: IpPacketDestination<I, &Self::DeviceId>,
        body: S,
    ) -> Result<(), IpSendFrameError<S>>
       where S: FragmentableIpSerializer<I, Buffer: BufferMut> + IpPacket<I>;
}

Trait for abstracting the IP layer for locally-generated traffic. That is, traffic generated by the netstack itself (e.g. ICMP, IGMP, or MLD).

NOTE: Due to filtering rules, it is possible that the device provided in meta will not be the device that final IP packet is actually sent from.

Required Methods

fn send_ip_packet_from_device<S>( &mut self, bindings_ctx: &mut BC, meta: SendIpPacketMeta<I, &Self::DeviceId, Option<SpecifiedAddr<I::Addr>>>, body: S, ) -> Result<(), IpSendFrameError<S>>

where S: TransportPacketSerializer<I>, S::Buffer: BufferMut,

Encapsulate and send the provided transport packet and from the device provided in meta.

fn send_ip_frame<S>( &mut self, bindings_ctx: &mut BC, device: &Self::DeviceId, destination: IpPacketDestination<I, &Self::DeviceId>, body: S, ) -> Result<(), IpSendFrameError<S>>

where S: FragmentableIpSerializer<I, Buffer: BufferMut> + IpPacket<I>,

Send an IP packet that doesn’t require the encapsulation and other processing of [send_ip_packet_from_device] from the device specified in meta.

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.
