pub struct MPlaceTy<'tcx, Prov: Provenance = AllocId> {
    mplace: MemPlace<Prov>,
    pub layout: TyAndLayout<'tcx>,
    pub align: Align,
}
Expand description

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

Fields§

§mplace: MemPlace<Prov>§layout: TyAndLayout<'tcx>§align: Align

rustc does not have a proper way to represent the type of a field of a repr(packed) struct: it needs to have a different alignment than the field type would usually have. So we represent this here with a separate field that “overwrites” layout.align. This means layout.align should never be used for a MPlaceTy!

Implementations§

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.

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.
