Struct rustc_infer::infer::region_constraints::leak_check::MiniGraph
source · 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
.

Layout§
Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...)
attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
