Struct rustc_mir_dataflow::move_paths::MovePathLookup

source ·
pub struct MovePathLookup<'tcx> {

    un_derefer: UnDerefer<'tcx>,
}
Expand description

Tables mapping from a place to its MovePathIndex.

Fields§

§locals: IndexVec<Local, Option<MovePathIndex>>§projections: FxHashMap<(MovePathIndex, ProjectionElem<AbstractOperand, AbstractType>), MovePathIndex>

projections are made from a base-place and a projection elem. The base-place will have a unique MovePathIndex; we use the latter as the index into the outer vector (narrowing subsequent search so that it is solely relative to that base-place). For the remaining lookup, we map the projection elem to the associated MovePathIndex.

§un_derefer: UnDerefer<'tcx>
