# This module should be included in order to turn an ApplicationWorker
|
|
# into a Subscriber.
|
|
# This module overrides the `perform` method and provides a better and
|
|
# safer interface for handling events via `handle_event` method.
|
|
#
|
|
# @example:
|
|
# class SomeEventSubscriber
|
|
# include ApplicationWorker
|
|
# include Gitlab::EventStore::Subscriber
|
|
#
|
|
# def handle_event(event)
|
|
# # ...
|
|
# end
|
|
# end
|
