1.  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)
