pub(crate) struct AllocMap<'tcx> {
alloc_map: FxHashMap<AllocId, GlobalAlloc<'tcx>>,
dedup: FxHashMap<(GlobalAlloc<'tcx>, usize), AllocId>,
next_id: AllocId,
}Fields§
§alloc_map: FxHashMap<AllocId, GlobalAlloc<'tcx>>Maps AllocIds to their corresponding allocations.
dedup: FxHashMap<(GlobalAlloc<'tcx>, usize), AllocId>Used to deduplicate global allocations: functions, vtables, string literals, …
The usize is a “salt” used by Miri to make deduplication imperfect, thus better emulating
the actual guarantees.
next_id: AllocIdThe AllocId to assign to the next requested ID.
Always incremented; never gets smaller.
