Fields

attributes: Attributes

The set of attributes associated with this graph node

Implementations

impl GraphNode

pub fn add_edge(&mut self, sink: GraphNodeRef) -> Result<&mut Edge, &mut Edge>

Adds an edge to this node. There can be at most one edge connecting any two graph nodes; the result indicates whether the edge is new (Ok) or already existed (Err). In either case, you also get a mutable reference to the Edge instance for the edge.

pub fn get_edge(&self, sink: GraphNodeRef) -> Option<&Edge>

Returns a reference to an outgoing edge from this node, if it exists.

pub fn get_edge_mut(&mut self, sink: GraphNodeRef) -> Option<&mut Edge>

Returns a mutable reference to an outgoing edge from this node, if it exists.

pub fn iter_edges(&self) -> impl Iterator<Item = (GraphNodeRef, &Edge)> + '_

pub fn edge_count(&self) -> usize
