pub struct StableGraph<N, E, Ty = Directed, Ix = DefaultIx> { /* private fields */ }
Expand description

StableGraph<N, E, Ty, Ix> is a graph datastructure using an adjacency list representation.

The graph does not invalidate any unrelated node or edge indices when items are removed.

StableGraph is parameterized over:

  • Associated data N for nodes and E for edges, also called weights. The associated data can be of arbitrary type.
  • Edge type Ty that determines whether the graph edges are directed or undirected.
  • Index type Ix, which determines the maximum size of the graph.

The graph uses O(|V| + |E|) space, and allows fast node and edge insert and efficient graph search.

It implements O(e’) edge lookup and edge and node removals, where e’ is some local measure of edge count.

  • Nodes and edges are each numbered in an interval from 0 to some number m, but not all indices in the range are valid, since gaps are formed by deletions.

  • You can select graph index integer type after the size of the graph. A smaller size may have better performance.

  • Using indices allows mutation while traversing the graph, see Dfs.

  • The StableGraph is a regular rust collection and is Send and Sync (as long as associated data N and E are).

  • Indices don’t allow as much compile time checking as references.

Depends on crate feature stable_graph (default). Stable Graph is still missing a few methods compared to Graph. You can contribute to help it achieve parity.

where F: FnMut(NodeIndex<Ix>, &'a N) -> Option<N2>, G: FnMut(EdgeIndex<Ix>, &'a E) -> Option<E2>,

Create a new StableGraph by mapping nodes and edges. A node or edge may be mapped to None to exclude it from the resulting graph.

Nodes are mapped first with the node_map closure, then edge_map is called for the edges that have not had any endpoint removed.

The resulting graph has the structure of a subgraph of the original graph. Nodes and edges that are not removed maintain their old node or edge indices.

Extend the graph from an iterable of edges.

Node weights N are set to default values. Edge weights E may either be specified in the list, or they are filled with default values.
