Expand description

Extra global state, available to the memory access hooks.

Fields§

§borrow_tracker_method: BorrowTrackerMethod

Borrow tracker method currently in use.

§next_ptr_tag: BorTag

Next unused pointer ID (tag).

§base_ptr_tags: FxHashMap<AllocId, BorTag>

Table storing the “base” tag for each allocation. The base tag is the one used for the initial pointer. We need this in a separate table to handle cyclic statics.

§next_call_id: CallId

Next unused call ID (for protectors).

§protected_tags: FxHashMap<BorTag, ProtectorKind>

All currently protected tags. An item is protected if its tag is in this set, and it has the “protected” bit set. We add tags to this when they are created with a protector in reborrow, and we remove tags from this when the call which is protecting them returns, in GlobalStateInner::end_call. See Stack::item_invalidated for more details.

§tracked_pointer_tags: FxHashSet<BorTag>

The pointer ids to trace

§tracked_call_ids: FxHashSet<CallId>

The call ids to trace

§retag_fields: RetagFields

Whether to recurse into datatypes when searching for pointers to retag.

§unique_is_unique: bool

Whether core::ptr::Unique gets special (Box-like) handling.
