Storage and network adapters for BEAM.

This module contains all adapter implementations that connect the crate::Node graph engine to external systems:

§Storage Adapters

§Storage Read/Write Split

Storage adapters that implement [Actor::try_clone_storage] are started as two actors by the Router: a read actor (receives Get) and a write actor (receives Put, BatchPut, Flush). Both share the same underlying store via Arc, so reads see committed writes immediately.

  • RedbStorage splits — the write actor’s spawn_blocking fsync no longer blocks the read actor’s concurrent Get queries.
  • MemoryStorage does not split — in-memory writes are synchronous (no fsync), so splitting provides no benefit and would break read-after-write ordering.

§Network Adapters

  • OutgoingWebsocketManager — outgoing WebSocket client manager
  • WsServer — incoming WebSocket server with optional TLS
  • WsConn — per-connection WebSocket actor (used by both client and server)
  • Multicast — UDP multicast LAN discovery
  • [WebRtcPeer] — WebRTC data channel P2P connection (feature-gated)

§Adapter Protocol

All adapters implement the crate::actor::Actor trait and receive [crate::message::Message] via the actor system. Storage adapters handle Get, Put, BatchPut, and Flush. Network adapters handle Put and Get by serializing to the wire format and forwarding to remote peers.
