Struct rustc_infer::infer::region_constraints::leak_check::SccUniverse[−][src]

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: UniverseIndex
Expand description

For some SCC S, the minimum universe of:

  • each region R in S
  • each SCC S1 such that S: S1
region: Option<Region<'tcx>>
Expand description

Some region that caused universe to be what it is.

Implementations

impl<'tcx> SccUniverse<'tcx>[src]

fn take_min(&mut self, universe: UniverseIndex, region: Region<'tcx>)[src]
