Struct DeferredLivenessSource

Source

struct DeferredLivenessSource<'a, 'tcx> {
    liveness: &'a mut LivenessValues,
    live_region_variances: &'a mut IndexVec<RegionVid, Option<ConstraintDirection>>,
    universal_regions: &'a UniversalRegions<'tcx>,
    deferred_locals_for_liveness: DeferredLocals<'tcx>,
    comp: LivenessComputation<'a, 'tcx>,
}

Expand description

A LivenessSource that will dynamically compute liveness on-demand when traversing the outlives graph. This allows avoiding computing liveness eagerly on many more locals than NLLs, which can be expensive.
