# serialization

I’m working with a backend returning a value attribute as part of a json payload. That attribute can potentially be of any primitive type or null. I started with a custom serializer :

class NullableAnySerializer : KSerializer<Any?> {
    override val descriptor: SerialDescriptor = // What should it be here?

    override fun serialize(encoder: Encoder, value: Any?) {
        when (value) {
            null -> encoder.encodeNull()
            is Float -> encoder.encodeFloat(value)
            is Boolean -> encoder.encodeBoolean(value)
            else -> throw IllegalStateException("unsupported type")
        }
    }

    override fun deserialize(decoder: Decoder): Any? {
        // What should it be here?
    }
}

I’m stuck at the level of descriptor and deserialize() what should I use in those places?

You could just use JsonPrimitive ?

Actually I think you should. It's a type the serializer will understand and it does what you describe.

I didn’t see this one before, thanks for the help 🙂
