getElementDescriptor

@ExperimentalSerializationApi
abstract fun getElementDescriptor(index: Int): SerialDescriptor(source)

Retrieves the descriptor of the child element for the given index. For the property of type T on the position i, getElementDescriptor(i) yields the same result as for T.serializer().descriptor, if the serializer for this property is not explicitly overridden with @Serializable(with = ...)`, Polymorphic or Contextual. This method can be used to completely introspect the type that the current descriptor describes.

Throws

for illegal index values.

if the current descriptor does not support children elements (e.g. is a primitive).
