Restricted(Id)
Visible only in the given crate-local module.

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). Read more

_: &DepNode<<Tcx as DepContext>::DepKind>
) -> Option<T>
default fn recover(
_: Tcx,
_: &DepNode<<Tcx 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 moresource§impl<T, R> InternIteratorElement<T, R> for T

Layout§
Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
