You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: solr_document_behavior.rb
    path of file: ./repos/hyrax/app/models/concerns/hyrax
    
    the code of the file until where you have to start completion: # frozen_string_literal: true
module Hyrax
  ##
  # @api public
  #
  # Hyrax extensions for +Blacklight+'s generated +SolrDocument+.
  #
  # @example using with +Blacklight::Solr::Document+
  #   class SolrDocument
  #     include 
    
    def embargo_enforced?
      return false if embargo_release_date.blank?

      indexed_embargo_visibility = first('visibility_during_embargo_ssim')
      # if we didn't index an embargo visibility, assume the release date means
      # it's enforced
      return true if indexed_embargo_visibility.blank?

      # if the visibility and the visibility during embargo are the same, we're
      # enforcing the embargo
      self['visibility_ssi'] == indexed_embargo_visibility
    end
