Trait petgraph::visit::NodeIndexable

pub trait NodeIndexable: GraphBase {
    fn node_bound(&self) -> usize;
    fn to_index(&self, a: Self::NodeId) -> usize;
    fn from_index(&self, i: usize) -> Self::NodeId;
}

The graph’s NodeIds map to indices

Required Methods

fn node_bound(&self) -> usize

Return an upper bound of the node indices in the graph (suitable for the size of a bitmap).

fn to_index(&self, a: Self::NodeId) -> usize

Convert a to an integer index.

fn from_index(&self, i: usize) -> Self::NodeId

Convert i to a node index
