Вы можете использовать все те же возможности валидации и инструменты, что и для Pydantic‑моделей, например разные типы данных и дополнительную валидацию через `Field()`.

// Validate returns nil if ef has valid fields, validation error otherwise.

You can use all the same validation features and tools you use for Pydantic models, like different data types and additional validations with `Field()`.
