Trait petgraph::visit::IntoNeighbors

pub trait IntoNeighbors: GraphRef {
    type Neighbors: Iterator<Item = Self::NodeId>;

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

Access to the neighbors of each node

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

  • Directed: All targets of edges from a.
  • Undirected: All other endpoints of edges connected to a.

Required Associated Types§

Required Methods§

source

fn neighbors(self, a: Self::NodeId) -> Self::Neighbors
