Armeria on Scala

• Unit 타입에 반환하는 함수의 반환값을 확인하지 않으면 컴파일러 워닝이 발생함
  • -Xfatal-warnings 옵션이 활성화 되면 컴파일도 실패됨
  • http4s-armeria/ArmeriaHttp4sHandler.scala at 39e3ae4847e071a80da3a8250ff6e405e58d55c6 · http4s/http4s-armeria · GitHub
• Function<? super HttpService, ? HttpService> 형태의 일 경우에 Scala Function에서 바로 형변환이 되지 않기 때문에 delegate => new MyHttpService(delegate) 를 해줘야 함
  • Decorator를 편하게 쓸수 있게 Scala Function용으로 하나 제공해주면 좋을것 같음
