Struct rustc_borrowck::region_infer::reverse_sccs::ReverseSccGraph
source · pub(crate) struct ReverseSccGraph {
graph: VecGraph<ConstraintSccIndex>,
scc_regions: FxHashMap<ConstraintSccIndex, Range<usize>>,
universal_regions: Vec<RegionVid>,
}Fields
graph: VecGraph<ConstraintSccIndex>scc_regions: FxHashMap<ConstraintSccIndex, Range<usize>>For each SCC, the range of universal_regions that use that SCC as
their value.
universal_regions: Vec<RegionVid>All of the universal regions, in grouped so that scc_regions can
index into here.

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.
