Fields§

§place: Place<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 PlaceTy!

Implementations§

source§

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

source

pub fn as_mplace_or_local(&self) -> Either<MPlaceTy<'tcx, Prov>, (usize, Local)>

A place is either an mplace or some local.

source

pub fn assert_mem_place(&self) -> MPlaceTy<'tcx, Prov>

Methods from Deref<Target = Place<Prov>>§

source

pub fn assert_local(&self) -> (usize, Local)

Asserts that this points to some local variable. Returns the frame idx and the variable idx.
