我可以在交互器 class 中将上下文用作 @context 吗？

Question

In some interactors, several functions are defined to be used in call function (I'm not using utility for organize such functions).
Is it fine to use @context instead of context in this situation?

Thanks for any help

As you can see from the source code context is just a simple accessor (getter method) declared by attr_reader :

module Interactor
  # Internal: Install Interactor's behavior in the given class.
  def self.included(base)
    base.class_eval do
      extend ClassMethods
      include Hooks

      # Public: Gets the Interactor::Context of the Interactor instance.
      attr_reader :context
    end
  end

There is thus almost no discernible difference between accessing the instance variable directly ( @context ) and through the context method as long as you're accessing it from within the class that includes this module.

class MyInteractor
  include Interactor

  def my_method
    @context
    # is the exact same as 
    context
    # except for the method call
  end
end
