pub struct MPlaceTy<'tcx, Prov = CtfeProvenance>where
Prov: Provenance,{
mplace: MemPlace<Prov>,
pub layout: TyAndLayout<'tcx, Ty<'tcx>>,

Expand description
A MemPlace with its layout. Constructing it is only possible in this module.
Fields§
§mplace: MemPlace<Prov>
§layout: TyAndLayout<'tcx, Ty<'tcx>>
Implementations§
source§impl<'tcx, Prov> MPlaceTy<'tcx, Prov>where
Prov: Provenance,
impl<'tcx, Prov> MPlaceTy<'tcx, Prov>where
Prov: Provenance,
sourcepub fn fake_alloc_zst(
layout: TyAndLayout<'tcx, Ty<'tcx>>
) -> MPlaceTy<'tcx, Prov>
pub fn fake_alloc_zst( layout: TyAndLayout<'tcx, Ty<'tcx>> ) -> MPlaceTy<'tcx, Prov>
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
) -> MPlaceTy<'tcx, Prov>
pub fn map_provenance( self, f: impl FnOnce(Prov) -> Prov ) -> MPlaceTy<'tcx, Prov>
Adjust the provenance of the main pointer (metadata is unaffected).
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.
