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: cookie.rb
    path of file: ./repos/artichoke/artichoke-backend/src/extn/stdlib/vendor/gen/cgi
    
    the code of the file until where you have to start completion: # frozen_string_literal: true
require_relative 'util'
class CGI
  # Class representing an HTTP cookie.
  #
  # In addition to its specific fields and methods, a Cookie instance
  # is a delegator to the array of its values.
  #
  # See RFC 2965.
  #
  # == Examples of use
  #   cookie1 = CGI::Cookie.new("name", "value1", "value2", ...)
  #   cookie1 = CGI::
    
    def to_s

      buf << "; path=#{@path}"     if @path
      buf << "; expires=#{CGI::rfc1123_date(@expires)}" if @expires
      buf << "; secure"            if @secure
      buf << "; HttpOnly"          if @httponly

    end

    # Parse a raw cookie string into a hash of cookie-name=>Cookie
    # pairs.
