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: kernel.rb
    path of file: ./repos/metasploit-framework/lib/rex/payloads/win32
    
    the code of the file until where you have to start completion: # -*- coding: binary -*-
module Rex
module Payload
    
  def self.construct(opts = {})
    payload = nil

    # Generate the recovery stub
    if opts['Recovery'] and Kernel::Recovery.respond_to?(opts['Recovery'], true)
      opts['RecoveryStub'] = Kernel::Recovery.send(opts['Recovery'], opts)
    end
