abstract class KeyEncoder[A] extends Serializable

A type class that provides a conversion from a value of type A to a string.

This type class will be used to create strings for JSON keys when encoding Map[A, ?] instances as JSON.

Note that if more than one value maps to the same string, the resuling JSON object may have fewer fields than the original map.
