Struct CoroutineSavedLocals

Source 
struct CoroutineSavedLocals(BitSet<Local>);
Expand description

The set of Locals that must be saved across yield points.

CoroutineSavedLocal is indexed in terms of the elements in this set; i.e. CoroutineSavedLocal::new(1) corresponds to the second local included in this set.
