Struct rustc_mir_dataflow::move_paths::MoveData

pub struct MoveData<'tcx> {
    pub move_paths: IndexVec<MovePathIndex, MovePath<'tcx>>,
    pub moves: IndexVec<MoveOutIndex, MoveOut>,
    pub loc_map: LocationMap<SmallVec<[MoveOutIndex; 4]>>,

}

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

impl<'tcx> MoveData<'tcx>

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

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>

Trait Implementations

impl<'tcx> Debug for MoveData<'tcx>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

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.
