Trait rs_graph::vec::NumberedIndexer

pub trait NumberedIndexer<I> {
    fn index(item: I) -> usize;
}

This trait maps nodes or edges to an index.

In contrast to vec::Indexer the mapping must be performed without access to the graph. Hence, the node_id and edge_id methods of an IndexGraph are not available.

Required Methods

fn index(item: I) -> usize

Implementors

• impl<N> NumberedIndexer<N> for NodeIndexer where     N: NumberedNode,

• impl<E> NumberedIndexer<E> for EdgeIndexer where     E: NumberedEdge,

• impl<E> NumberedIndexer<E> for BiEdgeIndexer where     E: BiNumberedEdge,
