/**
* Annotated callbacks that can be passed to an SDK running in the Privacy Sandbox.
*
* These can be used to provide the SDK with a channel to invoke app code, e.g. listeners. They
* should be public interfaces that only declare functions without implementation, and they may not
* extend any other interface. Callbacks run in the main thread by default.
*
* The allowed types are the same as for [PrivacySandboxInterface], except that functions may not
* return a value.
*
* Usage example:
* ```
* @PrivacySandboxCallback
* interface MyCallback {
* fun onComplete(response: Response)
* fun onClick(x: Int, y: Int)
* fun onCompleteInterface(myInterface: MyInterface)
* }
* ```
