object semiauto

Semi-automatic codec derivation.

This object provides helpers for creating io.circe.Decoder and io.circe.ObjectEncoder instances for case classes, "incomplete" case classes, sealed trait hierarchies, etc.

Typical usage will look like the following:

import io.circe._, io.circe.generic.semiauto._

case class Foo(i: Int, p: (String, Double))

object Foo {
  implicit val decodeFoo: Decoder[Foo] = deriveDecoder[Foo]
  implicit val encodeFoo: ObjectEncoder[Foo] = deriveEncoder[Foo]
}
