Struct LivenessInfo

Source 
struct LivenessInfo {
    saved_locals: CoroutineSavedLocals,
    live_locals_at_suspension_points: Vec<BitSet<CoroutineSavedLocal>>,
    source_info_at_suspension_points: Vec<SourceInfo>,
    storage_conflicts: BitMatrix<CoroutineSavedLocal, CoroutineSavedLocal>,
    storage_liveness: IndexVec<BasicBlock, Option<BitSet<Local>>>,
}

Fields§

§saved_locals: CoroutineSavedLocals

Which locals are live across any suspension point.

§live_locals_at_suspension_points: Vec<BitSet<CoroutineSavedLocal>>

The set of saved locals live at each suspension point.

§source_info_at_suspension_points: Vec<SourceInfo>

Parallel vec to the above with SourceInfo for each yield terminator.

§storage_conflicts: BitMatrix<CoroutineSavedLocal, CoroutineSavedLocal>

For every saved local, the set of other saved locals that are storage-live at the same time as this local. We cannot overlap locals in the layout which have conflicting storage.

§storage_liveness: IndexVec<BasicBlock, Option<BitSet<Local>>>

For every suspending block, the locals which are storage-live across that suspension point.
