/**
 * Description
 * This is the asynchronous version of GInitable; it behaves the same
 * in all ways except that initialization is asynchronous. For more details
 * see the descriptions on GInitable.
 * A class may implement both the GInitable and GAsyncInitable 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 NULL and
 * a set GError on failure.
 * A typical implementation might look something like this:
 * $(DDOC_COMMENT example)

     * Starts asynchronous initialization of the object implementing the
     * interface. This must be done before any real use of the object after
     * initial construction. If the object also implements GInitable you can
     * optionally call g_initable_init() instead.
     * When the initialization is finished, callback will be called. You can
     * then call g_async_initable_init_finish() to get the result of the
     * initialization.
     * Implementations may also support cancellation. If cancellable is not
     * NULL, then initialization can be cancelled by triggering the cancellable
     * object from another thread. If the operation was cancelled, the error
     * G_IO_ERROR_CANCELLED will be returned. If cancellable is not NULL, and
     * the object doesn't support cancellable initialization, the error
     * G_IO_ERROR_NOT_SUPPORTED will be returned.
     * If this function is not called, or returns with an error, then all
     * operations on the object should fail, generally returning the
     * error G_IO_ERROR_NOT_INITIALIZED.
     * Implementations of this method must be idempotent: i.e. multiple calls
     * to this function with the same argument should return the same results.
     * Only the first call initializes the object; further calls return the result
     * of the first call. This is so that it's safe to implement the singleton
     * pattern in the GObject constructor function.
     * For classes that also support the GInitable interface, the default
     * implementation of this method will run the g_initable_init() function
     * in a thread, so if you want to support asynchronous initialization via
     * threads, just implement the GAsyncInitable interface without overriding
     * any interface methods.
