+*   `ActiveJob::Base.deserialize` delegates to the job class.
 
     Since `ActiveJob::Base#deserialize` can be overridden by subclasses (like
     `ActiveJob::Base#serialize`) this allows jobs to attach arbitrary metadata
     when they get serialized and read it back when they get performed. Example:
 
-      class DeliverWebhookJob < ActiveJob::Base
-        def serialize
-          super.merge('attempt_number' => (@attempt_number || 0) + 1)
-        end
+        class DeliverWebhookJob < ActiveJob::Base
+          def serialize
+            super.merge('attempt_number' => (@attempt_number || 0) + 1)
+          end
 
-        def deserialize(job_data)
-          super
-          @attempt_number = job_data['attempt_number']
-        end
+          def deserialize(job_data)
+            super
+            @attempt_number = job_data['attempt_number']
+          end
 
-        rescue_from(TimeoutError) do |exception|
-          raise exception if @attempt_number > 5
-          retry_job(wait: 10)
+          rescue_from(TimeoutError) do |exception|
+            raise exception if @attempt_number > 5
+            retry_job(wait: 10)
+          end
         end
-      end
