Struct rustc_query_system::dep_graph::dep_node::WorkProductId
source · pub struct WorkProductId {
hash: Fingerprint,
}
Expand description
A “work product” corresponds to a .o
(or other) file that we
save in between runs. These IDs do not have a DefId
but rather
some independent path or string that persists between runs without
the need to be mapped or unmapped. (This ensures we can serialize
them even in the absence of a tcx.)

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).

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
