Struct rustc_middle::mir::query::ClosureOutlivesSubjectTy
source · pub struct ClosureOutlivesSubjectTy<'tcx> {
inner: Ty<'tcx>,
}
Expand description
Represents a ty::Ty
for use in ClosureOutlivesSubject
.
This abstraction is necessary because the type may include ReVar
regions,
which is what we use internally within NLL code, and they can’t be used in
a query response.
DO NOT implement TypeVisitable
or TypeFoldable
traits, because this
type is not recognized as a binder for late-bound region.

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).
default fn to_debug_str(&self, _: Tcx) -> String
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<P> IntoQueryParam<P> for P

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.
