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: stats.rb
    path of file: ./repos/ruby-packer/ruby/lib/rubygems/resolver
    
    the code of the file until where you have to start completion: # frozen_string_literal: true
class Gem::Resolver::Stats

  def initialize
    @max_depth = 0
    @max_requirements = 0
    @requirements = 0
    @backtracking = 0
    @iteratio
    
  def display
    $stdout.puts "=== Resolver Statistics ==="
    $stdout.printf PATTERN, "Max Depth", @max_depth
    $stdout.printf PATTERN, "Total Requirements", @requirements
    $stdout.printf PATTERN, "Max Requirements", @max_requirements
    $stdout.printf PATTERN, "Backtracking #", @backtracking
    $stdout.printf PATTERN, "Iteration #", @iterations
  end
