struct MiniGraph<'tcx> {
    nodes: FxIndexMap<Region<'tcx>, LeakCheckNode>,
    sccs: Sccs<LeakCheckNode, LeakCheckScc>,
}
Expand description

Represents the graph of constraints. For each R1: R2 constraint we create an edge R1 -> R2 in the graph.

Fields§

§nodes: FxIndexMap<Region<'tcx>, LeakCheckNode>

Map from a region to the index of the node in the graph.

§sccs: Sccs<LeakCheckNode, LeakCheckScc>

Map from node index to SCC, and stores the successors of each SCC. All the regions in the same SCC are equal to one another, and if S1 -> S2, then S1: S2.
