/** AsyncInitable - Asynchronously failable object initialization interface.
 * This is the asynchronous version of Initable; it behaves the same in all

 * descriptions on Initable.
 *
 * A class may implement both the Initable and AsyncInitable interfaces.
 *
 * Users of objects implementing this are not intended to use the interface
 * method directly; instead it will be used automatically in various ways. For
 * C applications you generally just call g_async_initable_new_async()
 * directly, or indirectly via a foo_thing_new_async() wrapper. This will call
 * g_async_initable_init_async() under the cover, calling back with nullptr and a
 * set GError on failure.

   *
   * When the initialization is finished, @a slot will be called. You can
   * then call init_finish() to get the result of the initialization.

   * Implementations may also support cancellation. Initialization can be
   * cancelled by triggering the @a cancellable object from another thread. If

   * operations on the object should fail, generally returning the error
   * Gio::IO_ERROR_NOT_INITIALIZED.

   * this function with the same argument should return the same results. Only

   * implementation of this method will run the Gio::Initable::init() method
