implicit final class Requiring[A] extends AnyVal

Implicit class providing requiring methods.
Implicit class providing requiring methods. This class is based on Predef.ensuring in the Scala standard library. The difference is that this class's methods throw IllegalArgumentExceptions rather than AssertionErrors.
An example adapted from Predef's documentation:
```
import akka.util.Helpers.Requiring

def addNaturals(nats: List[Int]): Int = {
  require(nats forall (_ >= 0), "List contains negative numbers")
  nats.foldLeft(0)(_ + _)
} requiring(_ >= 0)
```

def identityHashComparator[T <: AnyRef](comp: Comparator[T]): Comparator[T]

Create a comparator which will efficiently use System.identityHashCode, unless that happens to be the same for two non-equals objects, in which case the supplied “real” comparator is used; the comparator must be consistent with equals, otherwise it would not be an enhancement over the identityHashCode.
