XDag
A simple DAG (Directed Acyclic Graph) library
Note
This lib just provides a data-structure to store DAG with checking. It doesn't contain any algorithm about DAG.
Details
XDAG stores DAG by HashMap. it CANNOT ensure the order of children and edges
Docs
Examples
// Create a new DAG
let mut dag = Dag::new();
// insert 3 nodes with data '()'
dag.insert_node(2, ());
dag.insert_node(4, ());
dag.insert_node(3, ());
// insert 2 edges with data '()'
dag.insert_edge(2, 3, ()).unwrap();
dag.insert_edge(2, 4, ()).unwrap();
// Get all roots and leaves in DAG
let roots = dag.roots().map(|(id, _)| id).collect::<Vec<_>>();
let leaves = dag.leaves().map(|(id, _)| id).collect::<Vec<_>>();
assert_eq!(&roots, &[2]);
for id in [3, 4].iter() {
assert!(leaves.contains(id))

XDag
A simple DAG (Directed Acyclic Graph) libarary
Note
This lib just provides a data-structure to store DAG with checking. It doesn't contain any algorithm about DAG
Details
XDAG stores DAG by BTreeMap. Because it can ensure the order of edges and nodes.
Some Examples
// Create a new DAG
let mut dag = Dag::new();
// insert 3 nodes with data '()'
dag.insert_node(2, ());
dag.insert_node(4, ());
dag.insert_node(3, ());
// insert 2 edges with data '()'
dag.insert_edge(2, 3, ()).unwrap();
dag.insert_edge(2, 4, ()).unwrap();
// Get all roots and leaves in DAG
let roots = dag.roots().map(|(id, _)| id).collect::<Vec<_>>();
let leaves = dag.leaves().map(|(id, _)| id).collect::<Vec<_>>();
assert_eq!(&roots, &[2]);
for id in [3, 4].iter() {
assert!(leaves.contains(id))
}
