CyclicTy(Ty<'tcx>)

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

CyclicConst(&'tcx Const<'tcx>)
ProjectionMismatched(ExpectedFound<DefId>)
ExistentialMismatch(ExpectedFound<&'tcx List<Binder<'tcx, ExistentialPredicate<'tcx>>>>)

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

Trait Implementations

impl<'tcx> Clone for TypeError<'tcx>[src]

impl<'tcx> Debug for TypeError<'tcx>[src]

impl<'tcx> Display for TypeError<'tcx>[src]

Explains the source of a type err in a short, human readable way. This is meant to be placed in parentheses after some larger message. You should also invoke note_and_explain_type_err() afterwards to present additional details, particularly when it comes to lifetime-related errors.
