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: response.rb
    path of file: ./repos/ruby-oembed/lib/oembed
    
    the code of the file until where you have to start completion: module OEmbed
  # Contains oEmbed data about a URL, as returned by an OEmbed::Provider. The data
  # stored in Response instances can be accesse
    
    def self.create_for(raw, provider, url, format)
      fields = OEmbed::Formatter.decode(format, raw)

      resp_type = case fields['type']
        when 'photo' then OEmbed::Response::Photo
        when 'video' then OEmbed::Response::Video
        when 'link'  then OEmbed::Response::Link
        when 'rich'  then OEmbed::Response::Rich
        else              self
      end
