Incremental Topo

Crates.io Travis CI Documentation

A data structure for maintaining an topological ordering in an incremental fashion.

Usage

To use incremental-topo, first add this to your Cargo.toml:

[dependencies]
incremental-topo = "0.2.1"

Next, add this to your crate:

use incremental_topo::IncrementalTopo;

let mut dag = IncrementalTopo::new();

let cat = dag.add_node();
let dog = dag.add_node();
let human = dag.add_node();

assert_eq!(dag.len(), 3);

dag.add_dependency(&human, &dog).unwrap();
dag.add_dependency(&human, &cat).unwrap();
dag.add_dependency(&dog, &cat).unwrap();

let animal_order: Vec<_> = dag.descendants(&human).unwrap().collect();

assert_eq!(animal_order, vec![dog, cat]);
