Trait netstack3_core::udp::UdpBindingsTypes

source · 
pub trait UdpBindingsTypes: Sized {
    type ExternalData<I: Ip>: Debug + Send + Sync;
}
Expand description

The bindings context providing external types to UDP sockets.

§Discussion

We’d like this trait to take an I type parameter instead of using GAT to get the IP version, however we end up with problems due to the shape of [DatagramSocketSpec] and the underlying support for dual stack sockets.

This is completely fine for all known implementations, except for a rough edge in fake tests bindings contexts that are already parameterized on I themselves. This is still better than relying on Box<dyn Any> to keep the external data in our references so we take the rough edge.

Required Associated Types§
