Function pathfinding::undirected::connected_components::component_index

#[must_use]
pub fn component_index<N>(components: &[HashSet<N>]) -> HashMap<N, usize> where
    N: Clone + Hash + Eq, 

Locate vertices amongst disjoint sets.

• components are disjoint vertices sets.

This function returns a map between every vertex and the index of the set it belongs to in the components list.
