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: mysql_enum.rb
    path of file: ./repos/metasploit-framework/modules/auxiliary/admin/mysql
    
    the code of the file until where you have to start completion: ##
# This 
    
  def run
    # If we have a session make use of it
    if session
      print_status("Using existing session #{session.sid}")
      self.mysql_conn = session.client
      self.sock = session.client.socket
    else
      # otherwise fallback to attempting to login
      return unless mysql_login_datastore
    end
