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: field_object.rb
    path of file: ./repos/rails-graphql/lib/rails/graphql/type/object
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module Rails
  module GraphQL
    class Type
      # The introspection object for a field on objects and interfaces
      clas
    
          def deprecated_instance
            current.all_directives&.reverse_each do |item|
              return item if item.class <= deprecated_directive
            end

            nil
          end
