Hey folks
I have the following set of types

interface DynamoAttrs<T> {
    fun serialize(): Map<String, AttributeValue>
}

interface DynamoEntity<T : DynamoAttrs<T>> {
    fun deserialize(attrs: Map<String, AttributeValue>): T
}

data class Event(
    val id: Long,
    val message: String,
) : DynamoAttrs<Event> {
    override fun serialize(): Map<String, AttributeValue> = ...

    companion object : DynamoEntity<Event> {
        override fun deserialize(attrs: Map<String, AttributeValue>): Event = ...
    }
}

data class QueueItem<T : DynamoAttrs<T>>(
    val kind: QueueItemKind,
    val payload: T,
    val processed: Boolean = false
) : DynamoAttrs<QueueItem<T>> {

    override fun serialize(): Map<String, AttributeValue> = mapOf(
        "kind" to AttributeValue.builder().s(this.kind.name).build(),
        "payload" to AttributeValue.builder().m(this.payload.serialize()).build(),
        "processed" to AttributeValue.builder().bool(this.processed).build()
    )

    companion object : DynamoEntity<QueueItem<Any>> { --- how to declre sygnature properly to get it implementing DynamoEntity interface?
         fun deserialize(attrs: Map<String, AttributeValue>): QueueItem<E> {
            val kind = QueueItemKind.valueOf(
                attrs["kind"]?.s() ?: throw IllegalArgumentException(
                    "Failed to parse queue item kind. Attrs: $attrs"
                )
            )
            if (kind == QueueItemKind.ENTITY) {
                QueueItem(
                    kind,
                    Entity.deserialize(
                        attrs["payload"]?.m() ?: throw IllegalArgumentException(
                            "Failed to deserialize attributes to Entity. Attrs: $attrs"
                        )
                    ),
                    attrs["processed"]?.bool() ?: throw IllegalArgumentException(
                        "Failed to read 'processed' flag. Attrs: $attrs"
                    )
                )
            }
            throw IllegalStateException("Unexpected queue item kind $kind. Attrs: $attrs")
        }
    }
}

enum class QueueItemKind {
    ENTITY
}

is it possible?
