Struct rustc_middle::hir::place::Place [−][src]
A Place
represents how a value is located in memory.
This is an HIR version of rustc_middle::mir::Place
.
Fields
base_ty: Ty<'tcx>
The type of the PlaceBase
base: PlaceBase
The “outermost” place that holds this value.
projections: Vec<Projection<'tcx>>
How this place is derived from the base place.
Implementations
impl<'tcx> Place<'tcx>
[src]
pub fn deref_tys(&self) -> impl Iterator<Item = Ty<'tcx>> + '_
[src]
Returns an iterator of the types that have to be dereferenced to access
the Place
.
The types are in the reverse order that they are applied. So if
x: &*const u32
and the Place
is **x
, then the types returned are
*const u32
then &*const u32
.
pub fn ty(&self) -> Ty<'tcx>
[src]
Returns the type of this Place
after all projections have been applied.
pub fn ty_before_projection(&self, projection_index: usize) -> Ty<'tcx>
[src]
Returns the type of this Place
immediately before projection_index
th projection
is applied.
