그런 경우에는 일반적인 검증(예: 값이 `str`인지 검증한 뒤) 이후에 적용되는 **커스텀 검증 함수**를 사용할 수 있습니다.

`Annotated` 안에서 [Pydantic의 `AfterValidator`](https://docs.pydantic.dev/latest/concepts/validators/#field-after-validator)를 사용하면 이를 구현할 수 있습니다.

return values are mapped to functions returning a struct.

Not all Go types can be mapped to C types in a useful way.

   * <p>This class needs to write deserialized data into fields that are {@code final transient}.
   * Such writes will become impossible to perform in {@link #readObject} after JEP 500. Instead, we
   * must create a new instance with the desired field values, stash it in this field, and then
   * instruct Java serialization to use it instead of the originally created object.

We are importing the submodule `items` directly, instead of importing just its variable `router`.

This is because we also have another variable named `router` in the submodule `users`.

If we had imported one after the other, like:

```Python
from .routers.items import router
from .routers.users import router
```

      assertThat(task.get(UNEXPECTED_HANG_DELAY_MILLIS, MILLISECONDS)).isNull();

    // (b) Waiting for the single guard to become satisfied.
