User model은 data class 로, 각 유즈케이스 목록은 다음과 같다.
- CreateUserUseCase
- DeleteUserUseCase
- GetUserUseCase
- UpdateUserUseCase
해당 유즈케이스들은 suspend로 중단 함수를 통해 비동기 처리 가능하게 선언했으며, invoke 함수를 통해 클래스 인스턴스를 함수호출처럼 사용할 수 있게 만들었다.
또한, 각 유즈케이스의 결과를 알아야하는 것들은 Result<Unit> 을 반환하도록 만들었다.

DeleteUserUseCase: user 판별을 id:Long으로 변경
GetUserUseCase: 리턴 타입을 Result<User?> 로 변경하여 성공, 실패 여부를 추가했다. 성공 시 필요한 user 정보와 성공 상태를 같이 주고, 실패랄 경우 User? 에의해 null 이 들어오면서 실패 처리가 되는 것이다.
Result<T> 타입을 모두 반환하게 하여 명확한 에러 핸들링, 미래 확장성 대비, 코드의 일관성을 추구했다.
