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.

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.
