Properties
Methods
subscribe
subscribe(listener: () => void): () => void;Calls listener after each change of current, until the returned function is called.
run
run(...args: TArgs): Promise<TResult | undefined>;Runs the command. Starting a run clears error and failure. Resolves to the command's result, including a BridgeOutcome with a declared failure, or to undefined after an unexpected failure. error and failure are set only if no later run started meanwhile. It never rejects, so callers need no try/catch.
reset
reset(): void;Clears error and failure. Runs still in flight count as superseded: they settle without setting either, as when a later run starts.
dispose
dispose(): void;Stops publishing; runs still in flight settle without updating state.
