Fields§
§move_paths: IndexVec<MovePathIndex, MovePath<'tcx>>
§moves: IndexVec<MoveOutIndex, MoveOut>
§loc_map: LocationMap<SmallVec<[MoveOutIndex; 4]>>
Each Location l
is mapped to the MoveOut’s that are effects
of executing the code at l
. (There can be multiple MoveOut’s
for a given l
because each MoveOut is associated with one
particular path being moved.)
path_map: IndexVec<MovePathIndex, SmallVec<[MoveOutIndex; 4]>>
§rev_lookup: MovePathLookup<'tcx>
§inits: IndexVec<InitIndex, Init>
§init_loc_map: LocationMap<SmallVec<[InitIndex; 4]>>
Each Location l
is mapped to the Inits that are effects
of executing the code at l
.
init_path_map: IndexVec<MovePathIndex, SmallVec<[InitIndex; 4]>>
Implementations§
source§impl<'tcx> MoveData<'tcx>
impl<'tcx> MoveData<'tcx>
pub fn gather_moves( body: &Body<'tcx>, tcx: TyCtxt<'tcx>, param_env: ParamEnv<'tcx> ) -> Result<MoveData<'tcx>, (MoveData<'tcx>, Vec<(Place<'tcx>, MoveError<'tcx>)>)>
sourcepub fn base_local(&self, mpi: MovePathIndex) -> Option<Local>
pub fn base_local(&self, mpi: MovePathIndex) -> Option<Local>
For the move path mpi
, returns the root local variable (if any) that starts the path.
(e.g., for a path like a.b.c
returns Some(a)
)
pub fn find_in_move_path_or_its_descendants( &self, root: MovePathIndex, pred: impl Fn(MovePathIndex) -> bool ) -> Option<MovePathIndex>

Layout§
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.
