Fields
steps: &'tcx [CandidateStep<'tcx>]
The valid autoderef steps that could be find.
opt_bad_ty: Option<&'tcx MethodAutoderefBadTy<'tcx>>
If Some(T), a type autoderef reported an error on.
reached_recursion_limit: bool
If true
, steps
has been truncated due to reaching the
recursion limit.

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 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. Read moresourceimpl<T, R> InternIteratorElement<T, R> for T

attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
