Struct rustc_borrowck::borrow_set::BorrowSet

pub location_map: FxIndexMap<Location, BorrowData<'tcx>>,

pub locals_state_at_exit: LocalsStateAtExit,
}
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

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...)
attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
