Struct rustc_infer::infer::region_constraints::leak_check::SccUniverse

struct SccUniverse<'tcx> {
    universe: UniverseIndex,
    region: Option<Region<'tcx>>,
}

Tracks the “minimum universe” for each SCC, along with some region that caused it to change.

Fields

universe: UniverseIndex

For 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

impl<'tcx> SccUniverse<'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.
