Expand description
Spatial geometry constructors that appear in value position (INSERT
VALUES, WHERE equality) and synthesise a GeoJSON string literal directly
rather than resolving as registered scalar functions.
All constructors produce a SqlValue::String holding GeoJSON in the exact
shape the spatial read path parses (extract_geometry →
sonic_rs::from_str::<Geometry>), so an INSERTed geometry round-trips
through a subsequent SELECT of the GEOMETRY column.
