struct Gatherer<'b, 'a, 'tcx> {
    builder: &'b mut MoveDataBuilder<'a, 'tcx>,

Fields

builder: &'b mut MoveDataBuilder<'a, 'tcx>

loc: Location

Implementations

impl<'b, 'a, 'tcx> Gatherer<'b, 'a, 'tcx>

fn move_path_for(
    &mut self,
    place: Place<'tcx>
) -> Result<MovePathIndex, MoveError<'tcx>>

This creates a MovePath for a given place, returning an MovePathError if that place can’t be moved from.

NOTE: places behind references do not get a move path, which is problematic for borrowck.

Maybe we should have separate “borrowck” and “moveck” modes.

fn add_move_path(
    &mut self,
    base: MovePathIndex,
    elem: PlaceElem<'tcx>,
    mk_place: impl FnOnce(TyCtxt<'tcx>) -> Place<'tcx>
) -> MovePathIndex

fn create_move_path(&mut self, place: Place<'tcx>)

impl<'b, 'a, 'tcx> Gatherer<'b, 'a, 'tcx>

fn gather_statement(&mut self, stmt: &Statement<'tcx>)

fn gather_rvalue(&mut self, rvalue: &Rvalue<'tcx>)

fn gather_terminator(&mut self, term: &Terminator<'tcx>)

fn gather_operand(&mut self, operand: &Operand<'tcx>)

fn gather_move(&mut self, place: Place<'tcx>)

fn record_move(&mut self, place: Place<'tcx>, path: MovePathIndex)

fn gather_init(&mut self, place: PlaceRef<'tcx>, kind: InitKind)

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.
