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: deployment.rb
    path of file: ./repos/jets/lib/jets/cfn
    
    the code of the file until where you have to start completion: module Jets::Cfn
  class Deployment
    extend Memoist
    include Jets::AwsServices
    include Jets::Command::AwsHelpers
    include Jets::Command::ApiHelpers

    def initialize(options={})
      @o
    
    def delete_deployment
      resp = Jets::Api::Stack.retrieve("current")
      return if resp["error"] == "not_found"
      return unless resp["id"]
      resp = Jets::Api::Stack.delete(resp["id"])
      puts resp["message"] # IE: Stack demo-dev deleted
      resp
    rescue Jets::Api::RequestError => e
      puts "WARNING: Unable to delete release and stack. #{e.class}: #{e.message}"
    end
