Expand description
A MemPlace with its layout. Constructing it is only possible in this module.

§layout: TyAndLayout<'tcx>
Implementations§
source§impl<'tcx, Prov: Provenance> MPlaceTy<'tcx, Prov>
impl<'tcx, Prov: Provenance> MPlaceTy<'tcx, Prov>
sourcepub fn fake_alloc_zst(layout: TyAndLayout<'tcx>) -> Self
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.
sourcepub fn map_provenance(self, f: impl FnOnce(Prov) -> Prov) -> Self
pub fn map_provenance(self, f: impl FnOnce(Prov) -> Prov) -> Self
Adjust the provenance of the main pointer (metadata is unaffected).
pub(super) fn mplace(&self) -> &MemPlace<Prov>
pub fn ptr(&self) -> Pointer<Option<Prov>>
pub fn to_ref(&self, cx: &impl HasDataLayout) -> Immediate<Prov>

Layout§
Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
