135-139: Consider elevating log level for missing CityGML geometries.Currently logging at the info level when a feature lacks a CityGML geometry:
ctx.event_hub.info_log( None, format!("Feature {} does not have a citygml geometry", feature.id), );If this situation is unexpected or indicative of an issue, consider using a warning level to draw more attention.
145-146: Default values formax_lodandmin_lodmay lead to unintended behavior.Using default values of
max_lod = 4andmin_lod = 0might result in features with higher LODs being unfiltered unintentionally. Review whether these defaults align with the expected use cases, or consider making these parameters mandatory.
191-193: Add unit tests fortarget_lodsfunctionality.The current tests do not cover scenarios where
target_lodsis specified. Adding unit tests will help ensure that the filtering logic based ontarget_lodsworks as intended.Example Test Case:
- Test with
target_lodscontaining specific LODs and verify that only geometries with those LODs are retained.- Test with
target_lodsset to an empty vector to check handling of no LODs specified.Would you like assistance in writing these tests?

83-87: Fields in GeometryLodFilter are correctly initialized.
The fields max_lod, min_lod, and target_lods are properly assigned from the parameters.
95-97: target_lods field added to GeometryLodFilterParam struct.
The new field target_lods has been correctly added with the appropriate type Option<Vec<u8>>.
102-104: target_lods field added to GeometryLodFilter struct.
The addition of target_lods to the struct is correct and matches the corresponding parameter.
113-124: Potential exclusion of geometries without LOD values.
In the filtering logic, geometries without an LOD value are currently being discarded:
if let Some(lod) = g.lod {
target_lods.contains(&lod)
} else {
false
}If it is acceptable or desired to retain geometries without LODs, consider modifying the condition:
if let Some(lod) = g.lod {
target_lods.contains(&lod)
} else {
- false
+ true // Retain geometries without LOD values
}Alternatively, if geometries without LODs should be discarded, consider logging this scenario for better visibility.
Line range hint 159-164: Review LOD comparison logic for correctness.
The condition:
if highest_lod <= max_lod && lowest_lod >= min_lod {
//...
}Ensure that this logic correctly handles all edge cases, especially when highest_lod or lowest_lod is equal to max_lod or min_lod. There might be scenarios where features are incorrectly filtered due to strict inequality.
Suggestion:
Consider adding unit tests to cover these edge cases and confirm the behavior is as intended.

1759-1769: Consider documenting the relationship between targetLods and min/maxLodWhile the schema is technically correct, it would be beneficial to document how
targetLodsinteracts with the existingminLodandmaxLodproperties. For example:
- Are
targetLodsfiltered byminLodandmaxLod?- What happens if a target LOD is outside the min-max range?
- Which takes precedence in filtering?
Consider adding a description field to clarify the behavior:
"targetLods": { + "description": "Specific LOD values to filter for. If specified, only features with these LOD values will be included, subject to minLod and maxLod constraints if they are also specified.", "type": [ "array", "null" ], "items": { "type": "integer", "format": "uint8", "minimum": 0.0 } }

1759-1769: LGTM: Well-structured schema definition for targetLods
The schema definition for the new targetLods property is well-structured and consistent with the existing LOD-related properties:
- Correctly defined as an optional array (can be null)
- Proper type constraints for array items (uint8 with minimum 0)
- Maintains consistency with
minLodandmaxLodproperty definitions

341-343: Implement thecoords_itermethod for RectThe
coords_itermethod is currently unimplemented and will panic at runtime. Based on the type signature andcoords_count, it should return an iterator over the 8 coordinates of the rectangle.Consider implementing it like this:
- fn coords_iter(&self) -> Self::Iter<'_> { - todo!() - } + fn coords_iter(&self) -> Self::Iter<'_> { + iter::once(self.min()) + .chain(iter::once(Coordinate::new(self.max_x(), self.min_y(), self.min_z()))) + .chain(iter::once(self.max())) + .chain(iter::once(Coordinate::new(self.min_x(), self.max_y(), self.max_z()))) + }

24-31: Consider adding documentation for exterior vs regular iterationThe trait defines both regular (
coords_iter) and exterior (exterior_coords_iter) coordinate iteration, but the distinction between these methods isn't documented. Consider adding documentation to explain when to use each method, particularly for complex types like Polygon and MultiPolygon where the difference is significant.Add documentation like this:
pub trait CoordsIter { + /// Iterator type for all coordinates in the geometry, including interior rings type Iter<'a>: Iterator<Item = Coordinate<Self::ScalarXY, Self::ScalarZ>> where Self: 'a; + /// Iterator type for coordinates forming the exterior boundary of the geometry type ExteriorIter<'a>: Iterator<Item = Coordinate<Self::ScalarXY, Self::ScalarZ>> where Self: 'a;

43-52: LGTM: Improved type signature formatting
The reformatting of type signatures with explicit where clauses improves code readability while maintaining the same functionality. The changes are consistent across all implementations.
