java.lang.Object
- scala.annotation.Annotation
- - scala.deprecated
  - - akka.util.unused

All Implemented Interfaces:

scala.annotation.StaticAnnotation
```
public class unused
extends scala.deprecated
```
Marker for explicit or implicit parameter known to be unused, yet still necessary from a binary compatibility perspective or other reason. Useful in combination with -Ywarn-unused:explicits,implicits compiler options.
Extends 'deprecated' to make sure using a parameter marked @unused produces a warning, and not using a parameter marked @unused does not produce an 'unused parameter' warning.
This approach is deprecated in Scala 2.13 and scheduled to be removed in 2.14. Perhaps we should promote introducing an @unused to Scala? https://contributors.scala-lang.org/t/more-error-reporting-annotations/1681/7
