Trait petgraph::visit::IntoEdgesDirected

pub trait IntoEdgesDirected: IntoEdges + IntoNeighborsDirected {
    type EdgesDirected: Iterator<Item = Self::EdgeRef>;
    fn edges_directed(
        self, 
        a: Self::NodeId, 
        dir: Direction
    ) -> Self::EdgesDirected;
}

Access to all edges of each node, in the specified direction.

The edges are, depending on the direction and the graph’s edge type:

• Directed, Outgoing: All edges from a.
• Directed, Incoming: All edges to a.
• Undirected, Outgoing: All edges connected to a, with a being the source of each edge.
• Undirected, Incoming: All edges connected to a, with a being the target of each edge.

This is an extended version of the trait IntoNeighborsDirected; the former only iterates over the target node identifiers, while this trait yields edge references (trait EdgeRef).
