      • Abstract Interface: MainThreadObjectHandle<I, O extends object>

      An opaque source-runtime handle for an object realized on the main thread.

      A handle has logical identity and is serializable, but it is not the target object or an RPC stub. Capturing it in a main-thread function resolves it to the corresponding local target object. Development builds may wrap the background handle in a throwing guard solely to diagnose invalid access; that guard never forwards operations between runtimes.

      Type Parameters

      Accessors

      creationPayload

      Get Signature

      get creationPayload(): Readonly<I>

      The payload used to create the realized object.

      Readonly is a TypeScript contract; the value is not frozen at runtime.

      Returns

      Readonly<I>
