      # `Tapioca::Dsl::Compilers::GraphqlInputObject` generates RBI files for subclasses of
      # [`GraphQL::Schema::InputObject`](https://graphql-ruby.org/api-doc/2.0.11/GraphQL/Schema/InputObject).
      #
      # For example, with the following `GraphQL::Schema::InputObject` subclass:
      #
      # ~~~rb
      # class CreateCommentInput < GraphQL::Schema::InputObject
      #   argument :body, String, required: true
      #   argument :post_id, ID, required: true
      # end
      # ~~~
      #
      # this compiler will produce the RBI file `notify_user_job.rbi` with the following content:
      #
      # ~~~rbi
      # # create_comment.rbi
      # # typed: true
      # class CreateCommentInput
      #   sig { returns(String) }
      #   def body; end
      #
      #   sig { returns(String) }
      #   def post_id; end
      # end
      # ~~~
