Struct UdpAssoc 

pub struct UdpAssoc {
    pub socket: Arc<UdpSocket>,
    pub peer: SocketAddr,
    pub first_packets: Vec<Bytes>,
}

Fields

socket: Arc<UdpSocket>

Physical listener socket — vane-owned, shared via Arc with the listener’s recv loop. The fetch sends responses back to the peer through this socket; the listener demuxes inbound datagrams to the per-session forwarder via the dispatch table. See spec/crates/engine.md § udp_dispatch.

peer: SocketAddr

first_packets: Vec<Bytes>

Datagrams that triggered the cold-path FlowGraph entry, in arrival order. Length is 1 for the immediate cold-path; > 1 only when the listener went through the pending-peek state machine and the buffered datagrams replay together (per spec/crates/engine.md § Multi-packet peek). The L4Forward fetch sends every entry verbatim, in this order, before subscribing to the inbound hot-path channel.
