Implementations§

Source§

impl<W, G> ShortestPaths<W, G>
where G: GraphBase,

Source

pub fn on(graph: &G) -> ShortestPathsBuilder<'_, W, G, Identity, AnyAlgo>

Initializes the algorithm to be performed on given graph.

Source§

impl<W, G> ShortestPaths<W, G>
where G: GraphBase,

Source

pub fn source(&self) -> &G::VertexId

Source vertex where the search was started.

Source

pub fn dist<VI>(&self, to: VI) -> Option<&W>
where VI: Borrow<G::VertexId>,

Returns the path distance between the source vertex and the given vertex, or None if it’s not known.

There are two causes why the distance between two vertices is not known: (1) the vertices are not connected, or (2) the goal was reached before visiting the given vertex.

Source

pub fn reconstruct(&self, to: G::VertexId) -> PathReconstruction<'_, G> ⓘ

Returns an iterator over vertices on the path between the given vertex and the source vertex, in this order, or None if it wasn’t found.

There are two causes why the distance between two vertices is not known: (1) the vertices are not connected, or (2) the goal was reached before visiting the given vertex.
