semiauto

Semi-automatic codec derivation.

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

Typical usage will look like the following:

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

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

object Foo {
  implicit val decodeFoo: Decoder[Foo] = deriveFor[Foo].decoder
  implicit val encodeFoo: Encoder[Foo] = deriveFor[Foo].encoder
}
