Struct DistanceMap

pub struct DistanceMap { /* private fields */ }

Shortest-path distances from every point of a region to the nearest of several targets.

Implementations

impl DistanceMap

pub fn graph_vertices(&self) -> usize

Vertices of the visibility graph.

pub fn targets(&self) -> usize

How many targets the map was built from.

pub fn nearest( &self, point: Point2, ) -> Result<Result<Reach, Unreachable>, RouteError>

The nearest target from point and the route there.

Ok(Err(StartOutside)) for a point outside the region, Ok(Err(DisconnectedComponents)) for one no target can reach.

Errors

RouteError for a non-finite point or an undecidable predicate.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DistanceMap

fn fmt(&self, f: &mut Formatter<'_>) -> Result
