Gio.Task.report_error

function report_error(source_object: GObject.Object, callback: Gio.AsyncReadyCallback, source_tag: void, error: GLib.Error): void {
    // Gjs wrapper for g_task_report_error()
}
  

Creates a Gio.Task and then immediately calls Gio.Task.prototype.return_error on it. Use this in the wrapper function of an asynchronous method when you want to avoid even calling the virtual method. You can then use Gio.AsyncResult.prototype.is_tagged in the finish method wrapper to check if the result there is tagged as having been created by the wrapper method, and deal with it appropriately if so.
