Struct NodeRef 

pub struct NodeRef<'a, NodeData: Clone, EdgeData: Clone> { /* private fields */ }

Reference to a node in a Graph

The library guarantees that this references a valid node

Implementations

impl<'a, NodeData: Clone, EdgeData: Clone> NodeRef<'a, NodeData, EdgeData>

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

The data associated with the node

(a.k.a. the node weight)

pub fn id(&self) -> NodeId

The node’s identifier

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

pub fn iter_edges_from(&self) -> EdgesFrom<'a, NodeData, EdgeData>

Iterate over edges leaving this node

Order is unspecified.

pub fn iter_edges_to(&self) -> EdgesTo<'a, NodeData, EdgeData>

Iterate over edges entering this node

Order is unspecified.

Trait Implementations

impl<'a, NodeData: Clone + Clone, EdgeData: Clone + Clone> Clone for NodeRef<'a, NodeData, EdgeData>

fn clone(&self) -> NodeRef<'a, NodeData, EdgeData>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a, NodeData: Debug + Clone, EdgeData: Debug + Clone> Debug for NodeRef<'a, NodeData, EdgeData>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
