Trait Implementations§

source§

impl IntoDiagnosticArg for PolyTraitRef<'_>

source§

impl<'tcx> Key for PolyTraitRef<'tcx>

§

type CacheSelector = DefaultCacheSelector<Binder<'tcx, TraitRef<'tcx>>>

source§

fn query_crate_is_local(&self) -> bool

Given an instance of this key, what crate is it referring to? This is used to find the provider.
source§

fn default_span(&self, tcx: TyCtxt<'_>) -> Span

In the event that a cycle occurs, if no explicit span has been given for a query with key self, what span should we use?
source§

fn key_as_def_id(&self) -> Option<DefId>

If the key is a DefId or DefId–equivalent, return that DefId. Otherwise, return None.

fn ty_adt_id(&self) -> Option<DefId>

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.
