Struct rustc_data_structures::graph::vec_graph::VecGraph

source · 
pub struct VecGraph<N: Idx, const BR: bool = false> {
    node_starts: IndexVec<N, usize>,
    edge_targets: Vec<N>,
}
Expand description

A directed graph, efficient for cases where node indices are pre-existing.

If BR is true, the graph will store back-references, allowing you to get predecessors.

Fields§

§node_starts: IndexVec<N, usize>

Indices into edge_targets that signify a start of list of edges.

§edge_targets: Vec<N>

Targets (or sources for back refs) of edges
