Expand description

Labeling a graph can provide Weight information

§Examples

use graph_theory::GraphEngine;

Required Associated Types§

Source

type WeightRef: Deref<Target = V>

Remove edge by given edge-id or start and end node-id.

§Panics
  • No such ability

Not all graph engine supports insert edge.

§Examples
use graph_theory::GraphEngine;
Source

type WeightMut: DerefMut<Target = V>

Remove edge by given edge-id or start and end node-id.

§Panics
  • No such ability

Not all graph engine supports insert edge.

§Examples
use graph_theory::GraphEngine;

Required Methods§

Source

fn get_node_weight(&self, node: NodeID) -> Option<Self::WeightRef>

§Panics
  • No such ability

Not all graph engine supports insert edge.

§Examples
use graph_theory::GraphEngine;
Source

fn get_edge_weight<Q: Into<EdgeQuery>>( &self, edge: Q, ) -> Option<Self::WeightRef>

§Examples
use graph_theory::GraphEngine;
Source

Not all graph engine supports insert edge.

§Examples
use graph_theory::GraphEngine;
Source

fn set_edge_weight<Q: Into<EdgeQuery>>(&mut self, edge: Q, weight: V)

§Panics
  • No such ability

Not all graph engine supports insert edge.

§Examples
use graph_theory::GraphEngine;

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
