Implementations§

Source §

impl DistanceBfsResources

Source

pub fn new() -> Self

Create new distance BFS resources

Source

pub fn with_capacity(capacity: usize) -> Self

Create with capacity

Source

pub fn clear(&mut self)

Clear all resources for reuse

Source

pub fn bfs_within_radius<F>( &mut self, source: VertexId, radius: usize, adjacency: F, ) -> &HashSet<VertexId>
where F: Fn(VertexId) -> Vec<VertexId>,

Perform BFS from a source vertex

Returns the set of vertices reachable within the given radius.

§Arguments
