Struct rustc_middle::hir::place::Place

pub struct Place<'tcx> {
    pub base_ty: Ty<'tcx>,
    pub base: PlaceBase,
    pub projections: Vec<Projection<'tcx>>,
}

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>

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.

pub fn ty(&self) -> Ty<'tcx>

Returns the type of this Place after all projections have been applied.

pub fn ty_before_projection(&self, projection_index: usize) -> Ty<'tcx>

Returns the type of this Place immediately before projection_indexth projection is applied.

Trait Implementations

impl<'tcx> Clone for Place<'tcx>

fn clone(&self) -> Place<'tcx>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'tcx> Debug for Place<'tcx>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'tcx, __D: TyDecoder<I = TyCtxt<'tcx>>> Decodable<__D> for Place<'tcx>

fn decode(__decoder: &mut __D) -> Self

impl<'tcx, __E: TyEncoder<I = TyCtxt<'tcx>>> Encodable<__E> for Place<'tcx>

fn encode(&self, __encoder: &mut __E)

impl<'tcx> Hash for Place<'tcx>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'tcx, '__ctx> HashStable<StableHashingContext<'__ctx>> for Place<'tcx>

fn hash_stable( &self, __hcx: &mut StableHashingContext<'__ctx>, __hasher: &mut StableHasher )

impl<'tcx> PartialEq<Place<'tcx>> for Place<'tcx>

fn eq(&self, other: &Place<'tcx>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<'tcx> TypeFoldable<TyCtxt<'tcx>> for Place<'tcx>

fn try_fold_with<__F: FallibleTypeFolder<TyCtxt<'tcx>>>( self, __folder: &mut __F ) -> Result<Self, __F::Error>

The entry point for folding. To fold a value t with a folder f call: t.try_fold_with(f).

fn fold_with<F>(self, folder: &mut F) -> Selfwhere F: TypeFolder<I>,

A convenient alternative to try_fold_with for use with infallible folders. Do not override this method, to ensure coherence with try_fold_with.

impl<'tcx> TypeVisitable<TyCtxt<'tcx>> for Place<'tcx>

fn visit_with<__V: TypeVisitor<TyCtxt<'tcx>>>( &self, __visitor: &mut __V ) -> ControlFlow<__V::BreakTy>

The entry point for visiting. To visit a value t with a visitor v call: t.visit_with(v).

impl<'tcx> Eq for Place<'tcx>

impl<'tcx> StructuralEq for Place<'tcx>

impl<'tcx> StructuralPartialEq for Place<'tcx>

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.
