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: timings.rb
    path of file: ./repos/truffleruby/bench/asciidoctor/asciidoctor/lib/asciidoctor
    
    the code of the file until where you have to start completion: # encoding: UTF-8
module Asciidoctor
  class Timings
    def initialize
      @log = {}
      @timer
    
    def print_report to = $stdout, subject = nil
      to.puts %(Input file: #{subject}) if subject
      to.puts %(  Time to read and parse source: #{'%05.5f' % read_parse.to_f})
      to.puts %(  Time to convert document: #{'%05.5f' % convert.to_f})
      to.puts %(  Total time (read, parse and convert): #{'%05.5f' % read_parse_convert.to_f})
    end
  end
