Function bfs_distances 

pub fn bfs_distances<T, S>(
    graph: &S,
    start: usize,
    directed: bool,
) -> SparseResult<Array1<isize>>
where
    T: Float + Debug + Copy + 'static,
    S: SparseArray<T>,

Compute distances from a source vertex using BFS

Arguments

• graph - The graph as a sparse matrix (unweighted)
• start - Starting vertex
• directed - Whether the graph is directed

Returns

Array of distances from the start vertex to all other vertices

Examples

use scirs2_sparse::csgraph::bfs_distances;
use scirs2_sparse::csr_array::CsrArray;

let rows = vec![0, 1, 1, 2];
let cols = vec![1, 0, 2, 1];
let data = vec![1.0, 1.0, 1.0, 1.0];
let graph = CsrArray::from_triplets(&rows, &cols, &data, (3, 3), false).unwrap();

let distances = bfs_distances(&graph, 0, false).unwrap();
