Trait petgraph::visit::IntoEdges

pub trait IntoEdges: IntoEdgeReferences + IntoNeighbors {
    type Edges: Iterator<Item = Self::EdgeRef>;

    // Required method
    fn edges(self, a: Self::NodeId) -> Self::Edges;
}
Expand description

Access to the edges of each node.

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

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

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