Type Alias rustc_middle::query::queries::vtable_allocation::ProvidedValue

pub type ProvidedValue<'tcx> = AllocId;

This type alias specifies the type returned from query providers and the type used for decoding. For regular queries this is the declared returned type V, but arena_cache will use <V as Deref>::Target instead.

Aliased Type

struct ProvidedValue<'tcx>(pub NonZeroU64);

Fields

0: NonZeroU64

Trait Implementations

impl Clone for AllocId

fn clone(&self) -> AllocId

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AllocId

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

Formats the value using the given formatter.

impl<'tcx, D: TyDecoder<I = TyCtxt<'tcx>>> Decodable<D> for AllocId

fn decode(decoder: &mut D) -> Self

impl<'tcx, E: TyEncoder<I = TyCtxt<'tcx>>> Encodable<E> for AllocId

fn encode(&self, e: &mut E)

impl EraseType for AllocId

type Result = [u8; 8]

impl Hash for AllocId

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<'a> HashStable<StableHashingContext<'a>> for AllocId

fn hash_stable( &self, hcx: &mut StableHashingContext<'a>, hasher: &mut StableHasher )

impl IntoDiagnosticArg for AllocId

fn into_diagnostic_arg(self) -> DiagnosticArgValue<'static>

impl<'tcx> Lift<'tcx> for AllocId

type Lifted = AllocId

fn lift_to_tcx(self, _: TyCtxt<'tcx>) -> Option<Self>

impl Ord for AllocId

fn cmp(&self, other: &AllocId) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<AllocId> for AllocId

fn eq(&self, other: &AllocId) -> 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 PartialOrd<AllocId> for AllocId

fn partial_cmp(&self, other: &AllocId) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Provenance for AllocId

const OFFSET_IS_ADDR: bool = false

Says whether the offset field of Pointers with this provenance is the actual physical address.

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

Determines how a pointer should be printed.

fn get_alloc_id(self) -> Option<AllocId>

If OFFSET_IS_ADDR == false, provenance must always be able to identify the allocation this ptr points to (i.e., this must return Some). Otherwise this function is best-effort (but must agree with Machine::ptr_get_alloc). (Identifying the offset in that allocation, however, is harder – use Memory::ptr_get_alloc for that.)

fn join(_left: Option<Self>, _right: Option<Self>) -> Option<Self>

Defines the ‘join’ of provenance: what happens when doing a pointer load and different bytes have different provenance.

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

fn try_fold_with<F: FallibleTypeFolder<TyCtxt<'tcx>>>( self, _: &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: TypeFolder<TyCtxt<'tcx>>>(self, _: &mut F) -> Self

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 AllocId

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

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

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.
