Struct rustc_middle::ty::CratePredicatesMap
source · pub struct CratePredicatesMap<'tcx> {
pub predicates: FxHashMap<DefId, &'tcx [(Predicate<'tcx>, Span)]>,
}Expand description
The crate outlives map is computed during typeck and contains the
outlives of every item in the local crate. You should not use it
directly, because to do so will make your pass dependent on the
HIR of every item in the local crate. Instead, use
tcx.inferred_outlives_of() to get the outlives for a particular
item.
Fields
predicates: FxHashMap<DefId, &'tcx [(Predicate<'tcx>, Span)]>For each struct with outlive bounds, maps to a vector of the predicate of its outlive bounds. If an item has no outlives bounds, it will have no entry.

default fn fingerprint_style() -> FingerprintStyle
sourcedefault fn to_fingerprint(&self, tcx: Ctxt) -> Fingerprint
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

sourcedefault fn recover(Ctxt, &DepNode<<Ctxt as DepContext>::DepKind>) -> Option<T>
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 moresourceimpl<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.
