Trait petgraph::visit::IntoNeighborsDirected

pub trait IntoNeighborsDirected: IntoNeighbors {
    type NeighborsDirected: Iterator<Item = Self::NodeId>;
    fn neighbors_directed(
        self, 
        n: Self::NodeId, 
        d: Direction
    ) -> Self::NeighborsDirected;
}

Access to the neighbors of each node, through incoming or outgoing edges.

Depending on the graph’s edge type, the neighbors of a given directionality are:

• Directed, Outgoing: All targets of edges from a.
• Directed, Incoming: All sources of edges to a.
• Undirected: All other endpoints of edges connected to a.
