Scala extensions for the Kryo serialization library

Chill

Scala extensions for the Kryo serialization library.

Chill provides a a number of Kryo serializers and an Option-like type called the MeatLocker. The MeatLocker allows you to box Kryo-serializable objects and deserialize them lazily on the first call to get:

val boxedItem = MeatLocker(someItem)

// boxedItem is java.io.Serializable no matter what it contains.
val box = roundTripThroughJava(boxedItem)
box.get == boxedItem.get // true!

To retrieve the boxed item without caching the deserialized value, use meatlockerInstance.copy.
