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: integration.rb
    path of file: ./repos/dd-trace-rb/lib/datadog/tracing/contrib/action_view
    
    the code of the file until where you have to start completion: require_relative 'configuration/settings'
require_relative 'patcher'
require_relative '../integration'
require_relative '../rails/utils'

module Datadog
  module Tracing
    module
    
          def self.version
            # ActionView is its own gem in Rails 4.1+
            if Gem.loaded_specs['actionview']
              Gem.loaded_specs['actionview'].version
            # ActionView is embedded in ActionPack in versions < 4.1
            elsif Gem.loaded_specs['actionpack']
              action_pack_version = Gem.loaded_specs['actionpack'].version
              action_pack_version unless action_pack_version >= Gem::Version.new('4.1')
            end
