Function centralization_closeness_tmax 

pub fn centralization_closeness_tmax(n: u32, mode: CentralizationMode) -> f64

Theoretical maximum closeness centralization for a star graph.

For directed graphs, mode distinguishes IN/OUT from ALL. For undirected, mode should be All.

Returns NaN for n == 0.

Examples

use rust_igraph::{CentralizationMode, centralization_closeness_tmax};

// Undirected, 5 vertices: (5-1)*(5-2)/(2*5-3) = 12/7
let tmax = centralization_closeness_tmax(5, CentralizationMode::All);
assert!((tmax - 12.0 / 7.0).abs() < 1e-9);
