Trait DatagramFactory 

pub trait DatagramFactory:
    Send
    + Sync
    + 'static {
    // Required method
    fn bind(&self, addr: SocketAddr) -> Result<Box<dyn DatagramSocket>>;

    // Provided method
    fn backend_name(&self) -> &'static str { ... }
}

Runtime-agnostic factory that binds a DatagramSocket on the calling worker — the UDP sibling of AcceptorFactory. Injected into the serve path so a QUIC/h3 listener obtains a prime- or tokio-backed UDP socket without naming the concrete runtime. bind MUST be called from within a future already running on the target runtime’s worker.

Required Methods

fn bind(&self, addr: SocketAddr) -> Result<Box<dyn DatagramSocket>>

Provided Methods

fn backend_name(&self) -> &'static str

Name of the runtime backend this factory’s bind output must be polled on ("prime", "tokio", …). The default "unknown" is for factories that don’t declare one — test doubles and in-memory fakes never need to, since they have no reactor affinity to violate. Real backends override this so a caller-assembled RuntimeSelection (every field is pub) can be checked for a factory/runtime mismatch BEFORE the first poll, rather than discovering it via an opaque failure deep inside the wrong reactor (e.g. prime’s CURRENT_REACTOR is null when its UdpSocket is driven from a tokio worker).

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
