# 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 Gitlab::EventStore::Subscriber
#
# def handle_event(event)
# # ...
# end
# end
module Gitlab
module EventStore
module Subscriber

include ApplicationWorker
