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: config.rb
    path of file: ./repos/metasploit-framework/lib/rex/payloads/meterpreter
    
    the code of the file until where you have to start completion: # -*- coding: binary -*-
require 'rex/socket/x509_certificate'
require 'rex/post/meterpreter/extension_mapper'
require 'sec
    
  def session_block(opts)
    uuid = opts[:uuid].to_raw
    exit_func = Msf::Payload::Windows.exit_types[opts[:exitfunk]]

    # if no session guid is given then we'll just pass the blank
    # guid through. this is important for stageless payloads
    if opts[:stageless] == true || opts[:null_session_guid] == true
      session_guid = "\x00" * 16
    else
      session_guid = [SecureRandom.uuid.gsub(/-/, '')].pack('H*')
    end
