WritesMissingKeys

trait WritesMissingKeys[A] extends AnyRef

A trait signaling that a ConfigWriter can write missing (undefined) values.

ConfigWriters always produce a valid ConfigValue with their to method. This trait adds an extra toOpt method that parent writers can use in order to decide whether or not they should write a value using this writer.
