have anyone found a good way to deal with kotlinx.serialization and having proper typings? I.e., say I have data class Foo, which have a nicely typed parser fun parseFoo(text: String): Either<NonEmptyList<FooParseError>, Foo>, I'd like to serialize an instance of Foo directly, but when I deserialize, It would be nice to get the either. So I'm basically looking for something giving the pattern:

object FooSerializer : KNiceSerializer {
    override val descriptor: SerialDescriptor = PrimitiveSerialDescriptor("Foo", PrimitiveKind.STRING)

    override fun serialize(
        encoder: Encoder,
        value: Foo,
    ) { TODO() }

    override fun deserialize(decoder: Decoder): Either<NonEmptyList<FooParseError>, Foo>, { TODO() }
}

does this exist? If not is there a good way to do this? (Is it even possible, I'm assuming FooParseError might cause problems, even if such an interface was made)
