Trait petgraph::data::Build[−][src]

pub trait Build: Data + NodeCount {
    fn add_node(&mut self, weight: Self::NodeWeight) -> Self::NodeId;

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

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

A graph that can be extended with further nodes and edges

Required Methods

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

Provided Methods

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