module Xing::Serializers

  # Serializes a single page of a long paginated list. We assume the interface
  # provided by Kaminari: the object to be serialized needs to respond to:
  #
  #   current_page, limit_value, total_pages, total_count, each(and various
  #   Enumerable methods)

    include Paged

    def page_num
