Struct rustc_middle::mir::interpret::AllocMap

source · 
pub(crate) struct AllocMap<'tcx> {
    alloc_map: FxHashMap<AllocId, GlobalAlloc<'tcx>>,
    dedup: FxHashMap<GlobalAlloc<'tcx>, AllocId>,
    next_id: AllocId,
}

Fields§

§alloc_map: FxHashMap<AllocId, GlobalAlloc<'tcx>>

Maps AllocIds to their corresponding allocations.

§dedup: FxHashMap<GlobalAlloc<'tcx>, AllocId>

Used to ensure that statics and functions only get one associated AllocId. Should never contain a GlobalAlloc::Memory!

§next_id: AllocId

The AllocId to assign to the next requested ID. Always incremented; never gets smaller.
