Polymorphism is not supported

[zigzago]

I get this stacktrace when I try to serialize a inherited class (as described here https://github.com/Kotlin/kotlinx.serialization/blob/master/docs/polymorphism.md )

java.lang.ClassCastException: kotlinx.serialization.UnionKind$POLYMORPHIC cannot be cast to kotlinx.serialization.StructureKind

Nice, I got it. Will try to implement during week

I implemented it like in kotlinx.serialization.json by "classDiscriminator"(name of the class descriptor property in polymorphic serialization.)

You can look at it in tests
parsePolymorphismSealed()
stringifyPolymorphismSealed()
parsePolymorphismComplexHierarchies()
stringifyPolymorphismComplexHierarchies()
parsePolymorphism()
stringifyPolymorphism()
I take this from their readme https://github.com/Kotlin/kotlinx.serialization/blob/master/docs/polymorphism.md
