This library os being published to the macen central. Add library to your project as

libraryDependencies += "com.evolution" %% "derivation-circe" % "{version}"

Finally, define your own type, which derives circe instances

import evo.derivation.*
import evo.derivation.circe.*
import evo.derivation.config.Config
import java.util.UUID

@SnakeCase
@Discriminator("type")
enum User derives Config, EvoCodec:
    case AuthorizedClient(@Rename("client_id") id: UUID, name: String)
    case Anonymous

Transforms all the constructor and\or field names to the snake case

Defines discriminator field for serialization of sealed trait or enum

Renames single case class field or enum constructor
