//! Node-centrality measures for directed graphs.
//!
//! - [`mod@pagerank`] PageRank (Brin & Page 1998) — stationary distribution of
//! a damped random walk, computed by power iteration.
//! - [`mod@betweenness`] Betweenness centrality (Brandes 2001) — fraction of
//! shortest paths passing through each node.
//! - [`mod@closeness`] Closeness centrality (Bavelas 1950, Wasserman-Faust
//! normalisation) — inverse mean shortest-path distance to all reachable nodes.
