Struct EdgeRef 

pub struct EdgeRef<'a, NodeKey: Hash + Eq + Clone, NodeData: Clone, EdgeKey: Hash + Eq + Clone, EdgeData: Clone> { /* private fields */ }

Reference to an edge in a MapGraph

The library guarantees that this references a valid node

Implementations

impl<'a, NodeKey: Hash + Eq + Clone, NodeData: Clone, EdgeKey: Hash + Eq + Clone, EdgeData: Clone> EdgeRef<'a, NodeKey, NodeData, EdgeKey, EdgeData>

pub fn data(&self) -> &'a EdgeData

The data associated with this edge

(aka the edge weight)

pub fn key(&self) -> &'a EdgeKey

The edge’s identifier

You can use this to later reference the edge in the graph (if it still exists)

pub fn get_from_node(&self) -> NodeRef<'a, NodeKey, NodeData, EdgeKey, EdgeData>

Reference to the Node from which the edge starts

(aka the tail of the arc)

pub fn get_to_node(&self) -> NodeRef<'a, NodeKey, NodeData, EdgeKey, EdgeData>

Reference to the Node the edge points to

(aka the head of the arc)

impl<'a, NodeKey: Clone + Hash + Eq + Clone, NodeData: Clone + Clone, EdgeKey: Clone + Hash + Eq + Clone, EdgeData: Clone + Clone> Clone for EdgeRef<'a, NodeKey, NodeData, EdgeKey, EdgeData>

fn clone(&self) -> EdgeRef<'a, NodeKey, NodeData, EdgeKey, EdgeData>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)
