# serialization

Hello everyone!
I’m writing a library that depends on the serialization runtime. During this process, I need to determine that a serializer for a sealed class subtype belongs to a particular index concerning the rest of the cases.

I found kotlinx.serialization.SealedClassSerializer, which has a subclassSerializers: Array<KSerializer<out T>> constructor parameter but it’s not exposed. Otherwise, I could obtain the index based on that property.

Is there any other way to obtain a stable index of a sealed subclass serializer or its descriptor with any other APIs?
If the `SealedClassSerializer is the only way to go, would the Jetbrains compiler team be open to a PR to that class to expose fun indexOf(subClassSerializer: ...): Int or make subclassSerializers a public val?.

Any help is appreciated, thanks! 🙏
