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.

### Usage

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`:

```scala

libraryDependencies ++= Seq(

  "dev.hnaderi" %% "named-codec" % "@VERSION@"

)

// or circe module directly

libraryDependencies ++= Seq(

  "dev.hnaderi" %% "named-codec-circe" % "@VERSION@"

)

```

```scala

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 })

```
