Hi all. Using KotlinX, how do I serialize or desarialize a generic attribute?

@Serializable
data class Test<T>(
val attr: T
)

either pass in a serializer for

T

manually https://github.com/Kotlin/kotlinx.serialization/blob/master/docs/serializers.md#plugin-generated-generic-serializer or define a custom serializer https://github.com/Kotlin/kotlinx.serialization/blob/master/docs/serializers.md#custom-serializers-for-a-generic-type or set up contextual serialization https://github.com/Kotlin/kotlinx.serialization/blob/master/docs/serializers.md#contextual-serialization-and-generic-classes

Thanks @Adam S But i have another question How do I serializer and deserializer this class

@Serializable(with = BoxSerializer::class)
data class Box<T>(
val name: String
val contents: T
)

Im lost here

override fun deserialize(decoder: Decoder) = Box(dataSerializer.deserialize(decoder))

Generics can be really difficult with KxS, so I understand what you mean. What can

T

be? Do you have a class for it?

I'm using a messenger system. The stream follows publish the command-> read the command

@Serializable
data class Command <T> (
 @Serializeble(KUUID::class) val id: UUID,
  val status: CommandStatusEnum,
   val message: T
)

enum class CommandStatusEnum(val value: String) {
  Open("Open"),
  Closed("Closed"),
  Processing("Processing"),
  Error("Error")
}

object KUUID : KSerializer<UUID> {
  override val descriptor = PrimitiveSerialDescriptor("UUID", PrimitiveKind.STRING)
  override fun serialize(encoder: Encoder, value: UUID) = encoder.encodeString(value.toString())
  override fun deserialize(decoder: Decoder): UUID = UUID.fromString(decoder.decodeString())
}

the message can be any class, such as pro example, email class

@Serializable
data class EmailModel(
  @Serializable(KUUID::class) override val id: UUID,
  val active: Boolean,
  val address: String,
  @Serializable(KUUID::class) val associateFK: UUID
)

are the messages in JSON?

I will convert the objects to jsonObject,
