    # Adds +delay+, +delay_for+ and +delay_until+ methods to ActiveRecord to offload instance method
    # execution to Sidekiq.

    # @example

    # Please note, this is not recommended as this will serialize the entire
    # object to Redis.  Your Sidekiq jobs should pass IDs, not entire instances.
    # This is here for backwards compatibility with Delayed::Job only.
