Trait petgraph::data::DataMapMut

pub trait DataMapMut: DataMap {
    // Required methods
    fn node_weight_mut(
        &mut self,
        id: Self::NodeId,
    ) -> Option<&mut Self::NodeWeight>;
    fn edge_weight_mut(
        &mut self,
        id: Self::EdgeId,
    ) -> Option<&mut Self::EdgeWeight>;
}

Access node and edge weights mutably.

Required Methods
