Module traversal
Source - Bfs
- A breadth first search (BFS) of a graph.
- Dfs
- Visit nodes of a graph in a depth-first-search (DFS) emitting nodes in
preorder (when they are first discovered).
- DfsPostOrder
- Visit nodes in a depth-first-search (DFS) emitting nodes in postorder
(each node after all its descendants have been emitted).
- Topo
- A topological order traversal for a graph.
- WalkerIter
- A walker and its context wrapped into an iterator.
- Walker
- A walker is a traversal state, but where part of the traversal
information is supplied manually to each next call.
