Function full_citation 

pub fn full_citation(n: u32, directed: bool) -> IgraphResult<Graph>

Build the full citation graph on n vertices.

See the module documentation for the precise semantics of the directed flag.

Errors

• IgraphError::InvalidArgument — the n·(n−1)/2 edge count cannot be sized in usize (computed via usize::checked_mul so the failure mode is deterministic).

Examples

use rust_igraph::full_citation;

// Directed complete DAG on 4 vertices: 6 arcs forming a transitive
// closure where vertex i cites every j < i.
let dag = full_citation(4, true).unwrap();
assert_eq!(dag.vcount(), 4);
assert_eq!(dag.ecount(), 6);
assert!(dag.is_directed());

// Undirected → K_n (same edge multiset as full_graph(4, false, false)).
let k4 = full_citation(4, false).unwrap();
assert_eq!(k4.vcount(), 4);
assert_eq!(k4.ecount(), 6);
assert!(!k4.is_directed());
