Expand description
Reasons a method might not be object-safe.
Variants§
StaticMethod(Option<((String, Span), (String, Span))>)
e.g., fn foo()
ReferencesSelfInput(Option<Span>)
e.g., fn foo(&self, x: Self)
ReferencesSelfOutput
e.g., fn foo(&self) -> Self
ReferencesImplTraitInTrait(Span)
e.g., fn foo(&self) -> impl Sized
AsyncFn
e.g., async fn foo(&self)
WhereClauseReferencesSelf
e.g., fn foo(&self) where Self: Clone
Generic
e.g., fn foo<A>()
UndispatchableReceiver(Option<Span>)
the method’s receiver (self
argument) can’t be dispatched on

default fn fingerprint_style() -> FingerprintStyle
source§default fn to_fingerprint(&self, tcx: Tcx) -> Fingerprint
default fn to_fingerprint(&self, tcx: 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).
default fn to_debug_str(&self, _: Tcx) -> String
source§default fn recover(_: Tcx, _: &DepNode) -> Option<T>
default fn recover(_: Tcx, _: &DepNode) -> Option<T>
This method tries to recover the query key from the given
DepNode
,
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.source§impl<Q, K> Equivalent<K> for Q
