# Rails.queue is the application's queue. You can push a job onto
# the queue by:
#
# Rails.queue.push job
#
# A job is an object that responds to +run+. Queue consumers will
# pop jobs off of the queue and invoke the queue's +run+ method.
#
# Note that depending on your queue implementation, jobs may not
# be executed in the same process as they were created in, and
# are never executed in the same thread as they were created in.
#
# If necessary, a queue implementation may need to serialize your
# job for distribution to another process. The documentation of
# your queue will specify the requirements for that serialization.
