Description

When using generateKotlinNullableClasses, it becomes impossible to use toString in the debugger to view the full scope of all the fields that were actually accessed.

It would be nice if the generated functions held information whether or not the field were present or not, that way, a sane toString could be generated that checks if each field were present before adding it to the printed string.

Research direction

Start by locating the implementation of generateKotlinNullableClasses and the generated model toString logic. Inspect how field presence is represented, then verify that generated toString output includes only fields that were accessed and handles absent fields sensibly.
