require 'concurrent/executor/executor_service'
module Concurrent
# Indicates that the including `ExecutorService` guarantees
# that all operations will occur in the order they are post and that no
# two operations may occur simultaneously. This module provides no
# functionality and provides no guarantees. That is the responsibility
# of the including class. This module exists solely to allow the including
# object to be interrogated for its serialization status.
#
# @example
# class Foo
# include Concurrent::SerialExecutor
# end
#
# foo = Foo.new
#
# foo.is_a? Concurrent::ExecutorService #=> true
# foo.is_a? Concurrent::SerialExecutor #=> true
# foo.serialized? #=> true
#
# @!visibility private
module SerialExecutorService
include ExecutorService
# @!macro executor_service_method_serialized_question
#
# @note Always returns `true`
def serialized?
true
end
