Struct rustc_mir_dataflow::value_analysis::PlaceInfo

struct PlaceInfo {
    value_index: Option<ValueIndex>,
    proj_elem: Option<TrackElem>,
    first_child: Option<PlaceIndex>,
    next_sibling: Option<PlaceIndex>,
}

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

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.

Implementations

impl PlaceInfo

fn new(proj_elem: Option<TrackElem>) -> Self

Trait Implementations

impl Debug for PlaceInfo

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.
