Trait btree_dag::AddVertex

pub trait AddVertex<T> where
    T: Ord, {
    fn add_vertex(&mut self, x: T) -> Option<BTreeSet<T>>;
}

AddVertex adds the vertex x, if it is not there.

Example

use btree_dag::{BTreeDag, AddVertex, Vertices};
let mut dag: BTreeDag<String> = BTreeDag::new();
dag.add_vertex(String::from("origin"));

assert_eq!(dag.vertices().len(), 1);
