ZIO service layer pattern

While reading about ZIO-config in 2.0.4, the following pattern to create services caught my eye. I am copying it here for easy lookup. Enjoy.

val myLayer: ZLayer[PaymentRepo, Nothing, MyService] = ZLayer.scoped { for { repo <- ZIO.service[PaymentRepo] config <- ZIO.config(MyServiceImpl.config) ref <- Ref.make(MyState.Initial) impl <- ZIO.succeed(new MyServiceImpl(config, ref, repo)) _ <- impl.initialize _ <- ZIO.addFinalizer(impl.destroy) } yield impl }
