Expand description

A stability index, giving the stability level for items and methods.

Fields

stab_map: FxHashMap<LocalDefId, &'tcx Stability>

This is mostly a cache, except the stabilities of local items are filled by the annotator.

const_stab_map: FxHashMap<LocalDefId, &'tcx ConstStability>depr_map: FxHashMap<LocalDefId, DeprecationEntry>staged_api: FxHashMap<CrateNum, bool>

Maps for each crate whether it is part of the staged API.

active_features: FxHashSet<Symbol>

Features enabled for this crate.

Blanket Implementations

impl<T> Any for T where
T: 'static + ?Sized,

[src]

pub fn type_id(&self) -> TypeId

Gets the TypeId of self. Read more

[src]

impl<T> Borrow<T> for T where
T: ?Sized,

[src]

pub fn borrow(&self) -> &T

Immutably borrows from an owned value. Read more

[src]

impl<T> BorrowMut<T> for T where
T: ?Sized,

[src]

pub fn borrow_mut(&mut self) -> &mut T

[src]

impl<Ctxt, T> DepNodeParams<Ctxt> for T where
Ctxt: DepContext,
T: for<'a> HashStable<StableHashingContext<'a>> + Debug,

[src]

pub default fn fingerprint_style() -> FingerprintStyle

[src]

pub default fn to_fingerprint(&self, tcx: Ctxt) -> 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). Read more

[src]

pub default fn to_debug_str(&self, Ctxt) -> String

[src]

pub default fn recover(
Ctxt,
&DepNode<<Ctxt as DepContext>::DepKind>
) -> Option<T>

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. Read more

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.
