Struct rustc_middle::mir::interpret::allocation::ConstAllocation
source · pub struct ConstAllocation<'tcx>(pub Interned<'tcx, Allocation>);
Expand description
Interned types generally have an Outer
type and an Inner
type, where
Outer
is a newtype around Interned<Inner>
, and all the operations are
done on Outer
, because all occurrences are interned. E.g. Ty
is an
outer type and TyKind
is its inner type.
Here things are different because only const allocations are interned. This
means that both the inner type (Allocation
) and the outer type
(ConstAllocation
) are used quite a bit.

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
