BFS

reddb_server::storage::engine::pathfinding

Struct BFS

pub struct BFS;

Expand description

Breadth-First Search for unweighted shortest paths

Use when all edges have equal weight (or you only care about hop count). Time: O(V + E), Space: O(V)

Implementations§

impl BFS

pub fn shortest_path( graph: &GraphStore, source: &str, target: &str, ) -> ShortestPathResult

Find shortest path (by hop count) from source to target

pub fn reachable( graph: &GraphStore, source: &str, max_depth: usize, ) -> Vec<(String, usize)>

Find all nodes reachable from source within max_depth hops

pub fn traverse(graph: &GraphStore, source: &str) -> Vec<String>

BFS traversal returning all nodes in BFS order
