# asynchronous jobs:
#
# class HardWorker
# include Sidekiq::Worker
#
# def perform(*args)
# # do some work
# end
# end
#
# Then in your Rails app, you can do this:
#
# HardWorker.perform_async(1, 2, 3)
#
# Note that perform_async is a class method, perform is an instance method.

# :queue - use a named queue for this Worker, default 'default'
# :retry - enable the RetryJobs middleware for this Worker, default *true*
# :backtrace - whether to save any error backtrace in the retry payload to display in web UI,
# can be true, false or an integer number of lines to save, default *false*
