Struct petgraph::dot::Dot

pub struct Dot<'a, G> {
    graph: G,
    config: &'a [Config],
}

Dot implements output to graphviz .dot format for a graph.

Formatting and options are rather simple, this is mostly intended for debugging. Exact output may change.

Examples

use petgraph::Graph;
use petgraph::dot::{Dot, Config};

let mut graph = Graph::<_, ()>::new();
graph.add_node("A");
graph.add_node("B");
graph.add_node("C");
graph.add_node("D");
graph.extend_with_edges(&[
    (0, 1), (0, 2), (0, 3),
    (1, 2), (1, 3),
    (2, 3),
]);

println!("{:?}", Dot::with_config(&graph, &[Config::EdgeNoLabel]));

// In this case the output looks like this:
// 
// digraph {
//     0 [label="\"A\""]
//     1 [label="\"B\""]
//     2 [label="\"C\""]
//     3 [label="\"D\""]
//     0 -> 1
//     0 -> 2
//     0 -> 3
//     1 -> 2
//     1 -> 3
//     2 -> 3
// }

// If you need multiple config options, just list them all in the slice.

Fields
