Variants§

§

CyclicTy(I::Ty)

Instantiating a type variable with the given type would have created a cycle (because it appears somewhere within that type).

§

CyclicConst(I::Const)

§

ProjectionMismatched(ExpectedFound<I::DefId>)

§

ExistentialMismatch(ExpectedFound<I::BoundExistentialPredicates>)

§

ConstMismatch(ExpectedFound<I::Const>)

§

IntrinsicCast

§

ForceInlineCast

#[rustc_force_inline] functions must be inlined and must not be codegened independently, so casting to a function pointer must be prohibited.

§

TargetFeatureCast(I::DefId)

Safe #[target_feature] functions are not assignable to safe function pointers.
