I want to serialize a set of IP addresses. I have created an InetAddressSerializer, but how do I apply it to a set using annotations? I can't use (..).set in an annotiation.

@Serializable
data class SessionState(
        @Serializable(with = InstantSerializer::class)
        val start: Instant,
        val ips: Set<InetAddress>?
)

Ok, I've solved it like this now:

object InetAddressSetSerializer : KSerializer<Set<InetAddress>> by InetAddressSerializer.set

@Serializable(with = InetAddressSetSerializer::class)

but it doesn't seem desirable to me to do it like this every time a collection needs to be serialized
