Function extract_geometry

nodedb/src/data/executor/handlers/spatial.rs:297–309

Extract geometry from a document field. Handles three storage forms: - `Value::Geometry(g)` — native geometry (columnar path preserves type) - `Value::String(s)` — GeoJSON string (from SQL ST_Point → serialized) - `Value::Object(_)` — GeoJSON object (from schemaless doc storage)

(doc: &Value, field: &str)
