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: flatfile.rb
    path of file: ./repos/metasploit-framework/lib/msf/base/persistent_storage
    
    the code of the file until where you have to start completion: # -*- coding: binary -*-
module Msf
class PersistentStorage

# This class persists the state of the framework to a flatf
    
  def store(framework)
    # Open the supplied file path for writing.
    self.fd = File.new(self.path, "w")

    begin
      store_general(framework)
    ensure
      self.fd.close
    end
