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: dll_inject.rb
    path of file: ./repos/metasploit-framework/lib/msf/core/payload/windows
    
    the code of the file until where you have to start completion: # -*- coding: binary -*-
module Msf

#
# DllInject common module stub that is meant to be included in payloads that
# make use of DLL injection.

module Payload::Windows::DllInject

  include Msf::Payload::Windows

  def initialize(
    
  def handle_connection_stage(conn, opts = {})
    data = library_name + "\x00"

    begin
      encrypted_contents = ::File.binread(library_path)
      data += ::MetasploitPayloads::Crypto.decrypt(ciphertext: encrypted_contents)
    rescue
      print_error("Failed to load DLL: #{$!}.")

      # TODO: exception
      conn.close
      return
