Scala3 codec adapter that separates types and payloads
this is a tiny utility library that provides a simple codec adapter, that helps with creating codec that encode/decode type name separately.
This is mostly helpful in messaging applications, where payload and message types are separated; or for scenarios that you need to store a separate type name to enable type filtering.
This library is currently available for Scala binary version 3.3 on both JVM, JS and native.
To use the latest version, include the following in your build.sbt:
libraryDependencies ++= Seq(
"dev.hnaderi" %% "named-codec" % "@VERSION@"
)
// or circe module directly
libraryDependencies ++= Seq(
"dev.hnaderi" %% "named-codec-circe" % "@VERSION@"
)enum Data {
case A
case B(i: Int)
case C(s: String, i: Int)
}
import io.circe.generic.auto.*
import dev.hnaderi.namedcodec.*
val codec = CirceAdapter.of[Data]
codec.encode(Data.C("string", 101))
// EncodedMessage(name = "C", data = { "s": "string", i: 101 })
