pub type Key<'tcx> = (CrateNum, SimplifiedType);

Trait Implementations

impl AsLocalKey for (CrateNum, SimplifiedType)

type LocalKey = SimplifiedType

fn as_local_key(&self) -> Option<Self::LocalKey>

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

impl Key for (CrateNum, SimplifiedType)

type CacheSelector = DefaultCacheSelector<(CrateNum, SimplifiedType)>

fn default_span(&self, _: 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?

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>

impl<A: ParameterizedOverTcx, B: ParameterizedOverTcx> ParameterizedOverTcx for (A, B)

type Value<'tcx> = (<A as ParameterizedOverTcx>::Value<'tcx>, <B as ParameterizedOverTcx>::Value<'tcx>)

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.
