nauty-pet

Canonical graph labelling.

Leverages nauty and Traces to find canonical labellings for petgraph graphs.

Example

```rust use petgraph::graph::UnGraph; use nauty_pet::prelude::*;

// Two different vertex labellings for the tree graph with two edges let g1 = UnGraph::<(), ()>::fromedges([(0, 1), (1, 2)]); let g2 = UnGraph::<(), ()>::fromedges([(0, 1), (0, 2)]);

// There are two equivalent labellings let automorphisminfo = g1.clone().tryintoautom().unwrap(); asserteq!(automorphism_info.grpsize(), 2.);

// The canonical forms are identical let c1 = g1.clone().intocanon(); let c2 = g2.clone().intocanon(); assert!(c1.is_identical(&c2));

// Alternatively, we can use a dedicated struct for canonically // labelled graphs let c1 = CanonGraph::from(g1); let c2 = CanonGraph::from(g2); assert_eq!(c1, c2); ```

Features
