Implementations§

source§

impl<'tcx, Prov: Provenance> MPlaceTy<'tcx, Prov>

source

pub fn fake_alloc_zst(layout: TyAndLayout<'tcx>) -> Self

Produces a MemPlace that works for ZST but nothing else. Conceptually this is a new allocation, but it doesn’t actually create an allocation so you don’t need to worry about memory leaks.

source

pub fn map_provenance(self, f: impl FnOnce(Prov) -> Prov) -> Self

Adjust the provenance of the main pointer (metadata is unaffected).

source

pub(super) fn mplace(&self) -> &MemPlace<Prov>

source

pub fn ptr(&self) -> Pointer<Option<Prov>>

source

pub fn to_ref(&self, cx: &impl HasDataLayout) -> Immediate<Prov>
