##
# Automatically save and load any current attributes in the execution context
# so context attributes "flow" from Rails actions into any associated jobs.
# This can be useful for multi-tenancy, i18n locale, timezone, any implicit
# per-request attribute. See +ActiveSupport::CurrentAttributes+.
#
# @example
#
# # in your initializer
# require "sidekiq/middleware/current_attributes"
# Sidekiq::CurrentAttributes.persist(Myapp::Current)
#
