pysochrone::graph

Struct SpatialGraph 

Source 
pub struct SpatialGraph {
    pub graph: Arc<DiGraph<XmlNode, XmlWay>>,
    /* private fields */
}
Expand description

A graph bundled with a spatial index for O(log n) nearest-node queries. Build once via SpatialGraph::new, reuse for all lookups and routing. Both inner fields are reference-counted, so cloning a SpatialGraph is O(1).

Fields§

§graph: Arc<DiGraph<XmlNode, XmlWay>>
