Data used to compute the loans that are live at a given point in the CFG, when using
-Zpolonius=next
.
Records the CFG locations where each region is live. When we initially compute liveness, we use
an interval matrix storing liveness ranges for each region-vid.
A single integer representing a ty::Placeholder
.
Maps from ty::PlaceholderRegion
values that are used in the rest of
rustc to the internal PlaceholderIndex
values that are used in
NLL.
Stores the full values for a set of regions (in contrast to
LivenessValues
, which only stores those points in the where a
region is live). The full value for a region may contain points in
the CFG, but also free regions as well as bound universe
placeholders.
