Fields§
§location_map: FxIndexMap<Location, BorrowData<'tcx>>
The fundamental map relating bitvector indexes to the borrows
in the MIR. Each borrow is also uniquely identified in the MIR
by the Location
of the assignment statement in which it
appears on the right hand side. Thus the location is the map
key, and its position in the map corresponds to BorrowIndex
.
activation_map: FxIndexMap<Location, Vec<BorrowIndex>>
Locations which activate borrows. NOTE: a given location may activate more than one borrow in the future when more general two-phase borrow support is introduced, but for now we only need to store one borrow index.
local_map: FxIndexMap<Local, FxIndexSet<BorrowIndex>>
Map from local to all the borrows on that local.
locals_state_at_exit: LocalsStateAtExit
