Function walktrap_with_options 

pub fn walktrap_with_options(
    graph: &Graph,
    weights: Option<&[f64]>,
    opts: WalktrapOptions,
) -> IgraphResult<WalktrapResult>

Run Walktrap with a custom WalktrapOptions.

weights = None runs the unweighted variant; otherwise see walktrap_weighted for the weight contract.

Errors

• IgraphError::Unsupported if graph.is_directed().
• IgraphError::InvalidArgument for opts.steps == 0, weight length mismatch, negative / non-finite weights, or a vertex whose incident-edge total weight underflows to zero.

Examples

use rust_igraph::{Graph, walktrap_with_options, WalktrapOptions};

let mut g = Graph::with_vertices(3);
g.add_edge(0, 1).unwrap();
g.add_edge(1, 2).unwrap();
g.add_edge(2, 0).unwrap();
let opts = WalktrapOptions { steps: 6 };
let r = walktrap_with_options(&g, None, opts).unwrap();
assert_eq!(r.nb_clusters, 1);
