Function personalized_pagerank_vs 

pub fn personalized_pagerank_vs(
    graph: &Graph,
    reset_vids: &[u32],
    damping: f64,
) -> IgraphResult<Vec<f64>>

Personalized PageRank with a vertex-set reset distribution.

Convenience wrapper around personalized_pagerank that constructs a uniform reset vector over the specified reset_vids. Teleportation probability is distributed equally among the given vertices.

Counterpart of igraph_personalized_pagerank_vs().

Errors

• InvalidArgument if reset_vids is empty.
• InvalidArgument if any vertex in reset_vids is out of range.
• InvalidArgument if damping is not in (0, 1).

Examples

use rust_igraph::{Graph, personalized_pagerank_vs};

let mut g = Graph::with_vertices(4);
g.add_edge(0, 1).unwrap();
g.add_edge(1, 2).unwrap();
g.add_edge(2, 3).unwrap();
g.add_edge(3, 0).unwrap();
// Teleport only to vertices 0 and 1
let pr = personalized_pagerank_vs(&g, &[0, 1], 0.85).unwrap();
let sum: f64 = pr.iter().sum();
assert!((sum - 1.0).abs() < 1e-9);
// Vertices 0 and 1 should get more rank than 2 and 3
assert!(pr[0] + pr[1] > pr[2] + pr[3]);
