Struct rustc_infer::infer::region_constraints::leak_check::SccUniverse
source · [−]struct SccUniverse<'tcx> {
universe: UniverseIndex,
region: Option<Region<'tcx>>,
}Expand description
Tracks the “minimum universe” for each SCC, along with some region that caused it to change.
Fields
universe: UniverseIndexFor some SCC S, the minimum universe of:
- each region R in S
- each SCC S1 such that S: S1
region: Option<Region<'tcx>>Some region that caused universe to be what it is.
Implementations
sourceimpl<'tcx> SccUniverse<'tcx>
impl<'tcx> SccUniverse<'tcx>
sourcefn take_min(&mut self, universe: UniverseIndex, region: Region<'tcx>)
fn take_min(&mut self, universe: UniverseIndex, region: Region<'tcx>)
If universe is less than our current universe, then update
self.universe and self.region.
