Struct rustc_middle::hir::place::Place

pub base_ty: Ty<'tcx>,

}
Expand description
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§
source§impl<'tcx> Place<'tcx>
impl<'tcx> Place<'tcx>
sourcepub fn deref_tys(&self) -> impl Iterator<Item = Ty<'tcx>> + '_
pub fn deref_tys(&self) -> impl Iterator<Item = Ty<'tcx>> + '_
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
.
sourcepub fn ty(&self) -> Ty<'tcx>
pub fn ty(&self) -> Ty<'tcx>
Returns the type of this Place
after all projections have been applied.
sourcepub fn ty_before_projection(&self, projection_index: usize) -> Ty<'tcx>
pub fn ty_before_projection(&self, projection_index: usize) -> Ty<'tcx>
Returns the type of this Place
immediately before projection_index
th projection
is applied.

source§fn has_vars_bound_at_or_above(&self, binder: DebruijnIndex) -> bool
fn has_vars_bound_at_or_above(&self, binder: DebruijnIndex) -> bool
true
if self
has any late-bound regions that are either
bound by binder
or bound by some binder outside of binder
.
If binder
is ty::INNERMOST
, this indicates whether
there are any late-bound regions that appear free. Read moresource§fn has_vars_bound_above(&self, binder: DebruijnIndex) -> bool
fn has_vars_bound_above(&self, binder: DebruijnIndex) -> bool
true
if this type has any regions that escape binder
(and
hence are not bound by it). Read moresource§fn has_escaping_bound_vars(&self) -> bool
fn has_escaping_bound_vars(&self) -> bool
true
if this type has regions that are not a part of the type.
For example, for<'a> fn(&'a i32)
return false
, while fn(&'a i32)
would return true
. The latter can occur when traversing through the
former. Read morefn has_type_flags(&self, flags: TypeFlags) -> bool

something which is needed when forcing DepNode
s during red-green
evaluation. The query system will only call this method if
fingerprint_style()
is not FingerprintStyle::Opaque
.
It is always valid to return None
here, in which case incremental
compilation will treat the query as having changed instead of forcing it. Read moresource§impl<T, R> InternIteratorElement<T, R> for T

Layout§
Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...)
attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
