Trait petgraph::visit::IntoNeighbors

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

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

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

type Neighbors: Iterator<Item = Self::NodeId>

Required Methods

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

Return an iterator of the neighbors of node a.

Object Safety

This trait is not object safe.
