source · pub struct ConstQualifs {

}Expand description
The result of the mir_const_qualif query.
Each field (except error_occurred) corresponds to an implementer of the Qualif trait in
rustc_const_eval/src/transform/check_consts/qualifs.rs. See that file for more information on each
Qualif.

default fn fingerprint_style() -> FingerprintStyle

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

) -> 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: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
