Trait DataMap 

pub trait DataMap: Data {
    // Required methods
    fn node_weight(&self, id: Self::NodeId) -> Option<&Self::NodeWeight>;
    fn edge_weight(&self, id: Self::EdgeId) -> Option<&Self::EdgeWeight>;
}

Access node and edge weights (associated data).

Required Methods

fn node_weight(&self, id: Self::NodeId) -> Option<&Self::NodeWeight>

fn edge_weight(&self, id: Self::EdgeId) -> Option<&Self::EdgeWeight>

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
