`current_user`의 타입을 Pydantic 모델 `User`로 선언한다는 점에 주목하세요.

이는 함수 내부에서 자동 완성과 타입 체크에 도움을 줍니다.

/// tip | 팁

요청 본문도 Pydantic 모델로 선언된다는 것을 기억하실지도 모릅니다.

여기서 **FastAPI**는 `Depends`를 사용하고 있기 때문에 혼동하지 않습니다.

///

/// check | 확인

이 의존성 시스템이 설계된 방식은 모두 `User` 모델을 반환하는 서로 다른 의존성(서로 다른 "dependables")을 가질 수 있도록 합니다.

해당 타입의 데이터를 반환할 수 있는 의존성이 하나만 있어야 하는 것으로 제한되지 않습니다.
