Module scalar

Scalar references onto a parent GeoArrow array.

For all “native” GeoArrow scalar types, (all types defined in this module) it is O(1) and allocation-free for any coordinate access.

For “serialized” scalars emitted from the GenericWkbArray, WkbViewArray, GenericWktArray, and WktViewArray, there is an initial parsing step when accessing the scalar from the GeoArrowArrayAccessor trait.

All scalars implement geo_traits. You can iterate through geometry parts directly using the APIs exposed by geo_traits. Or, for simplicity at the cost of a memory copy, you can use the traits defined in geo_traits::to_geo to convert these scalars to [geo_types] objects (though keep in mind ).

Converting to [geo_types]

You can convert these scalars to [geo_types] objects using the geo_traits::to_geo traits.

There are a couple drawbacks:

• geo_types only supports 2D geometries. Any other dimensions will be dropped.
• geo_types doesn’t support empty points. This is why both ToGeoGeometry::to_geometry and ToGeoGeometry::try_to_geometry exist. The former will panic on any empty points.
