Struct rustc_mir_dataflow::move_paths::MovePathLookup
source · pub struct MovePathLookup<'tcx> {
locals: IndexVec<Local, MovePathIndex>,
projections: FxHashMap<(MovePathIndex, ProjectionElem<AbstractOperand, AbstractType>), MovePathIndex>,
un_derefer: UnDerefer<'tcx>,
}
Expand description
Tables mapping from a place to its MovePathIndex.
Fields§
§locals: IndexVec<Local, 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>

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.
