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: run.rb
    path of file: ./repos/rails_async_migrations/lib/rails_async_migrations/migration
    
    the code of the file until where you have to start completion: # to run actual migration we need to require the migration files
module 
    
      def initialize(direction, version)
        @direction = direction
        @version = version
        @migration = migration_from version

        ensure_data_consistency
        require "#{Rails.root}/#{migration.filename}" if defined? Rails
      end
