A modern programming language that makes developers happier.

kotlinlang

I have a sealed class hierarchy, but the input JSON (externally defined) uses `_type` instead of `type` as the discriminator. Doing `@SerialName("_type") val type: String` doesn't seem to work. A JSON content-based polymorphic deserialization seems like overkill for this. Is there some annotations that will work short of that?

Does <https://kotlin.github.io/kotlinx.serialization/kotlinx-serialization-json/kotlinx-serialization-json/kotlinx.serialization.json/-json-class-discriminator/index.html#:~:text=serialization.json%2FJsonClassDiscriminator-,JsonClassDiscriminator,classDiscriminator%20property.|@JsonClassDiscriminator> work for your case?

Yes, that's what I was looking for, thanks!
