Struct rustc_infer::infer::region_constraints::leak_check::MiniGraph

pub(in infer::region_constraints::leak_check) struct MiniGraph<'tcx> {
    nodes: FxHashMap<Region<'tcx>, LeakCheckNode>,
    sccs: Sccs<LeakCheckNode, LeakCheckScc>,
}

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

Fields

nodes: FxHashMap<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.

Implementations

impl<'tcx> MiniGraph<'tcx>

pub(in infer::region_constraints::leak_check) fn new<'a>(
    tcx: TyCtxt<'tcx>,
    undo_log: impl Iterator<Item = &'a UndoLog<'tcx>>,
    verifys: &[Verify<'tcx>]
) -> Self where
    'tcx: 'a, 

pub(in infer::region_constraints::leak_check) fn iterate_undo_log<'a>(
    tcx: TyCtxt<'tcx>,
    undo_log: impl Iterator<Item = &'a UndoLog<'tcx>>,
    verifys: &[Verify<'tcx>],
    each_edge: impl FnMut(Region<'tcx>, Region<'tcx>)
) where
    'tcx: 'a, 

Invokes each_edge(R1, R2) for each edge where R2: R1

    nodes: &mut FxHashMap<Region<'tcx>, LeakCheckNode>,
    r: Region<'tcx>
