Function famous_names 

pub fn famous_names() -> &'static [&'static str]

Canonical (lowercase) names of every famous graph supported by famous. Aliases are not duplicated here — each graph appears once under its primary name. famous itself still accepts every alias.

use rust_igraph::famous_names;

let names = famous_names();
assert!(names.contains(&"petersen"));
assert!(names.contains(&"zachary"));
