Struct rustc_mir_dataflow::value_analysis::PlaceInfo

source · 
struct PlaceInfo<'tcx> {
    ty: Ty<'tcx>,
    value_index: Option<ValueIndex>,
    proj_elem: Option<TrackElem>,
    first_child: Option<PlaceIndex>,
    next_sibling: Option<PlaceIndex>,
}
Expand description

This is the information tracked for every PlaceIndex and is stored by Map.

Together, first_child and next_sibling form an intrusive linked list, which is used to model a tree structure (a replacement for a member like children: Vec<PlaceIndex>).

Fields§

§ty: Ty<'tcx>

Type of the referenced place.

§value_index: Option<ValueIndex>

We store a ValueIndex if and only if the placed is tracked by the analysis.

§proj_elem: Option<TrackElem>

The projection used to go from parent to this node (only None for root).

§first_child: Option<PlaceIndex>

The left-most child.

§next_sibling: Option<PlaceIndex>

Index of the sibling to the right of this node.
