Expand description

A graph that can be extended with further nodes and edges

Required Methods§

source

fn add_node(&mut self, weight: Self::NodeWeight) -> Self::NodeId

source

fn update_edge( &mut self, a: Self::NodeId, b: Self::NodeId, weight: Self::EdgeWeight ) -> Self::EdgeId

Add or update the edge from a to b. Return the id of the affected edge.

Provided Methods§

source

fn add_edge( &mut self, a: Self::NodeId, b: Self::NodeId, weight: Self::EdgeWeight ) -> Option<Self::EdgeId>

Add a new edge. If parallel edges (duplicate) are not allowed and the edge already exists, return None.

Object Safety§

This trait is not object safe.
