is it possible to write a custom serializer (kotlinx.serialization) for serializing only, and not overriding deserialize? I get an error if I don't specifically override deserialize too. Alternatively, how can I write the deserialize method to use the default or built-in deserializer? (this is for a data class, not a primitive). There's no super to leverage. Thank you.

You could also write error("This type cannot be deserialized.") in the deserialization function.

I guess you could implement SerializationStrategy instead of KSerializer if you just want to go one-way. Depending on which APIs you interact with that might be limiting, but I think they've tried to make stuff flexible enough to support that use-case.

For falling back to the built-in, have you tried delegating to YourClass.serializer().deserialize(...)?

thanks @russhwolf - both your suggestions helped. Yes a new SerializationStrategy was ultimately needed, because I'm serializing a class not a primitive. Also, yes YourClass.serializer().deserialize(...) appears to work, I had been expecting something like super.deserialize() because this is an override method. Really appreciate it!
