Hi @Brian_McQueen,
Sorry for the late reply. The documentation is implying that fields which are structs will only be considered empty if the type implements Zeroer. Fields with non-struct types like booleans, numbers, maps, slices, and pointers are handled directly by the driver. You can see the code to determine if a field should be considered empty here and an example showing that primitives are automatically handled without any additional code here.
