Type Alias rustc_middle::query::queries::hir_owner_parent::ProvidedValue

pub type ProvidedValue<'tcx> = HirId;

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 owner: OwnerId,
    pub local_id: ItemLocalId,
}

Fields

owner: OwnerId

local_id: ItemLocalId

Trait Implementations

impl<'tcx> DepNodeParams<TyCtxt<'tcx>> for HirId

fn fingerprint_style() -> FingerprintStyle

fn to_fingerprint(&self, tcx: TyCtxt<'tcx>) -> Fingerprint

This method turns the parameters of a DepNodeConstructor into an opaque Fingerprint to be used in DepNode. Not all DepNodeParams support being turned into a Fingerprint (they don’t need to if the corresponding DepNode is anonymous).

fn to_debug_str(&self, tcx: TyCtxt<'tcx>) -> String

fn recover(tcx: TyCtxt<'tcx>, dep_node: &DepNode) -> Option<Self>

This method tries to recover the query key from the given DepNode, something which is needed when forcing DepNodes 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.

impl EraseType for HirId

type Result = [u8; 8]

impl Key for HirId

type CacheSelector = DefaultCacheSelector<HirId>

fn default_span(&self, tcx: TyCtxt<'_>) -> Span

In the event that a cycle occurs, if no explicit span has been given for a query with key self, what span should we use?

fn key_as_def_id(&self) -> Option<DefId>

If the key is a DefId or DefId–equivalent, return that DefId. Otherwise, return None.

fn ty_adt_id(&self) -> Option<DefId>

impl<'tcx> Lift<'tcx> for HirId

type Lifted = HirId

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

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

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 HirId

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).

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.
