1. final case class Boxing[-A, +B](fun: (A) ⇒ B) extends AnyVal with Product with Serializable

2. trait Delegation[A, B] extends AnyRef

   

   A typeclass which witnesses that type A can be wrapped into trait or abstract class B

3. trait LowPrioBoxing extends AnyRef

   

4. trait LowPrioUnboxing extends AnyRef

   

5. final class NOpt[+A] extends AnyVal with Serializable

   

   Like Opt but does have a counterpart for Some(null).

6. final class Opt[+A] extends AnyVal with Serializable

   

   Like Option but avoids boxing.

   Like Option but avoids boxing. No value is represented internally using null. Therefore, there is no equivalent for Some(null).

7. final class OptRef[+A >: Null] extends AnyVal with Serializable

   

   Like Opt but has better Java interop thanks to the fact that wrapped value has type A instead of Any.

   Like Opt but has better Java interop thanks to the fact that wrapped value has type A instead of Any. For example, Scala method defined like this:

   def takeMaybeString(str: OptRef[String]): Unit

   will be seen by Java as:

   public void takeMaybeString(String str);

   and null will be used to represent absence of value.

   This comes at the cost of A having to be a nullable type.

9. trait SealedEnumCompanion[T] extends AnyRef

   

   Base trait for companion objects of sealed traits that serve as enums, i.e.

   Base trait for companion objects of sealed traits that serve as enums, i.e. their only values are case objects. For example:

   sealed trait SomeEnum
   object SomeEnum extends SealedEnumCompanion[SomeEnum] {
     case object FirstValue extends SomeEnum
     case object SecondValue extends SomeEnum
     case object ThirdValue extends SomeEnum
   
     // it's important to give explicit type here
     val values: List[SomeEnum] = caseObjects
   }

10. final case class Unboxing[+A, -B](fun: (B) ⇒ A) extends AnyVal with Product with Serializable
