## 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>

source

#### pub fn gather_moves( body: &Body<'tcx>, tcx: TyCtxt<'tcx>, param_env: ParamEnv<'tcx>, filter: impl Fn(Ty<'tcx>) -> bool ) -> MoveData<'tcx>

source

#### 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)`)

source

#### 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.
