/// tip

`async` 함수와 일반 함수 모두 사용할 수 있습니다.

**FastAPI**는 일반 의존성과 마찬가지로 각각의 함수를 올바르게 처리할 것입니다.

///

## `yield`와 `try`를 사용하는 의존성 { #a-dependency-with-yield-and-try }

`yield`를 사용하는 의존성에서 `try` 블록을 사용한다면, 의존성을 사용하는 도중 발생한 모든 예외를 받을 수 있습니다.

예를 들어, 다른 의존성이나 *경로 처리*의 중간에 데이터베이스 트랜잭션 "롤백"이 발생하거나 다른 오류가 발생한다면, 해당 예외를 의존성에서 받을 수 있습니다.
