fn fingerprint_style() -> FingerprintStyle
Source§fn to_fingerprint(&self, tcx: TyCtxt<'tcx>) -> Fingerprint
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).

Source§fn recover(tcx: TyCtxt<'tcx>, dep_node: &DepNode) -> Option<Self>
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 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<E> Encodable<E> for LocalDefIdwhere
