Function number_connected_components

pub fn number_connected_components<G>(graph: G) -> usize
where
    G: GraphProp + IntoNeighborsDirected + Visitable + IntoNodeIdentifiers,
    G::NodeId: Eq + Hash,

Given a graph, return the number of connected components of the graph.

Arguments:

• graph - The graph object to run the algorithm on

Example

use rustworkx_core::petgraph::{Graph, Undirected};
use rustworkx_core::connectivity::number_connected_components;

let graph = Graph::<(), (), Undirected>::from_edges([(0, 1), (1, 2), (3, 4)]);
assert_eq!(number_connected_components(&graph), 2);
