Fields

config: EnvoyConfig

envoy_key: String

envoy_tx: UnboundedSender<ToEnvoyMessage>

actors: Arc<Mutex<HashMap<String, HashMap<u32, SharedActorEntry>>>>

actors_notify: Arc<Notify>

live_tunnel_requests: Arc<Mutex<HashMap<[u8; 8], String>>>

pending_hibernation_restores: Arc<Mutex<HashMap<String, Vec<HibernatingWebSocketMetadata>>>>

ws_tx: Arc<Mutex<Option<UnboundedSender<WsTxMessage>>>>

http_ws_tx: Arc<Mutex<Option<HttpConnectionTx>>>

connection_session: AtomicU64

The currently connected WebSocket session, or zero while disconnected.

Session IDs are actor-client-local and never cross the wire. Remote SQLite transactions use them to prevent a statement from being admitted on a replacement WebSocket after the server-side connection (and its SQLite handle) has already been torn down.

next_connection_session: AtomicU64

connection_session_tx: Sender<u64>

protocol_metadata: Arc<Mutex<Option<ProtocolMetadata>>>

shutting_down: AtomicBool

last_ping_ts: AtomicI64

Epoch ms timestamp of the most recent ping packet received from the engine. Used by EnvoyHandle::is_ping_healthy to surface a dead engine link to upstream health checks. Zero means no ping has been received yet.

stopped_tx: Sender<bool>
