Bu destek hâlâ **Pydantic** sayesinde vardır; çünkü Pydantic, [`dataclasses` için dahili destek](https://docs.pydantic.dev/latest/concepts/dataclasses/#use-of-stdlib-dataclasses-with-basemodel) sunar.

Таким чином його схема з'явиться в інтерфейсі користувача документації API:

## Dataclasses у вкладених структурах даних { #dataclasses-in-nested-data-structures }

Можна поєднувати `dataclasses` з іншими анотаціями типів, щоб створювати вкладені структури даних.

  *  HorizontalPodAutoscaler was Beta in 1.1 and is GA in 1.2 .
     * <code>apiVersion: autoscaling/v1 </code>is now available.  Changes in this version are:

HorizontalPodAutoscalerSpec was replaced by TargetCPUUtilizationPercentage
which is an integer.
        * ScaleRef of type SubresourceReference in HorizontalPodAutoscalerSpec which

## Dataclasses en Estructuras de Datos Anidadas { #dataclasses-in-nested-data-structures }

También puedes combinar `dataclasses` con otras anotaciones de tipos para crear estructuras de datos anidadas.
