Variants§
ProjectionTy
A projection <Type as Trait>::AssocType
.
Can get normalized away if monomorphic enough.
InherentTy
An associated type in an inherent impl
OpaqueTy
An opaque type (usually from impl Trait
in type aliases or function return types)
Can only be normalized away in RevealAll mode
WeakTy
A type alias that actually checks its trait bounds. Currently only used if the type alias references opaque types. Can always be normalized away.
UnevaluatedConst
An unevaluated const coming from a generic const expression.
ProjectionConst
An unevaluated const coming from an associated const.

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<Q, K> Equivalent<K> for Q
