Change Summary
I could have implemented this simplification for all cases (perhaps in
GenerateSchema._apply_single_annotation
or similar) but I don't want to break any unusual scenarios, plus this kind of situation is pretty uncommon in the general case (you're not really going to annotate a field asAny | <other>
), it only makes sense when parameterizingT | <other>
withAny
/Never
.This has the added benefit of creating simplified JSON Schemas, as shown in the test.
