source · [−]

pub struct ConstQualifs {
    pub has_mut_interior: bool,

Expand description

The result of the mir_const_qualif query.

Each field (except error_occured) 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.

source

pub default fn fingerprint_style() -> FingerprintStyle

source

pub default fn to_fingerprint(&self, tcx: Ctxt) -> 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

source

pub default fn to_debug_str(&self, Ctxt) -> String

source

pub default fn recover(
Ctxt,
&DepNode<<Ctxt 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 more
