Ok I think I see the issue, you are saying for example you have ``` let mut variant = VariantBuilder::new(); let mut parent_object_builder = variant.new_object(); let mut child_object_builder1 = parent_object_builder.new_object(); ... let mut child_object_builder2 = parent_object_builder.new_object(); ... ``` and lets say we for got to put `self.check_pending_field();` as the first line of `ObjectBuilder::new_object()`, that would mean `child_object_builder1` would get put in the `parent_object_builder.pending` field. Then when the `parent_object_builder.new_object()` is called to build `child_object_builder2` the `parent_object_builder.pending` is overwritten with the pending field name of the new field for child object 2 so it never gets `self.fields.insert()` called on it making the `child_object1` not get created correctly/missing, so in the same function scope that it gets overwritten, it gets `drop`ped, so we can just run the `check_pending_field` it when it gets dropped/overwritten Seems kind of a workaround, but it may work -- This is an automated message from the Apache Git Service.
