На самом деле, `Query`, `Path` и другие функции, которые вы увидите в дальнейшем, создают объекты подклассов общего класса `Param`, который сам по себе является подклассом `FieldInfo` из Pydantic.

И `Field` (из Pydantic), и `Body`, оба возвращают объекты подкласса `FieldInfo`.

У класса `Body` есть и другие подклассы, с которыми вы ознакомитесь позже.
