			==Accessors==
			You can use attr_reader (readonly), attr_writer(writeonly) and attr_accessor(both) to create get/settters. This is convenient to reduce the amount of typing. For instance.
			<syntaxhighlight lang="rb">
			# typed: true

			class PageDataError < StandardError
			extend T::Sig
			attr_reader :status, :detail

			sig { params(status: Integer, detail: String).void }
			def initialize(status:, detail:)
			@status = status
			@detail = detail
			super(detail)
