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: uploaded_file.rb
    path of file: ./repos/ferrocarril/mruby-gems/vendor/ruby/2.6.0/gems/rack-2.0.7/lib/rack/multipart
    
    the code of the file until where you have to start completion: module Rack
  module Multipart
    class UploadedFile
      # The filename, *not* including the path, of the "uploaded" file
      attr_reader :original_filename

      # The content type of the "uploaded" file
      attr_accessor :content_type

      def initialize(path, content_type = "text/plain", binary = false)
        raise "#{path} file does not exist" unless ::File.exist?(path)
        @content_type = content_type
        @original_filename = ::File.basename(path)
        @tempfile = Tempfile.new([@original
    
      def initialize(path, content_type = "text/plain", binary = false)
        raise "#{path} file does not exist" unless ::File.exist?(path)
        @content_type = content_type
        @original_filename = ::File.basename(path)
        @tempfile = Tempfile.new([@original_filename, ::File.extname(path)], encoding: Encoding::BINARY)
        @tempfile.binmode if binary
        FileUtils.copy_file(path, @tempfile.path)
      end

      def path
        @tempfile.path
      end
      alias_method :local_path, :path

      def respond_to?(*args)
        super or @tempfile.respond_to?(*args)
      end

      def method_missing(method_name, *args, &block) #:nodoc:
        @tempfile.__send__(method_name, *args, &block)
      end
    end
