Variants§

§

CodeCycle(Vec<Obligation<'tcx, Predicate<'tcx>>, Global>)

Inherently impossible to fulfill; this trait is implemented if and only if it is already implemented.

§

CodeSelectionError(SelectionError<'tcx>)

§

CodeProjectionError(MismatchedProjectionTypes<'tcx>)

§

CodeSubtypeError(ExpectedFound<Ty<'tcx>>, TypeError<'tcx>)

§

CodeConstEquateError(ExpectedFound<Const<'tcx>>, TypeError<'tcx>)

§

CodeAmbiguity

Fields

§overflow: bool

Overflow reported from the new solver -Ztrait-solver=next, which will be reported as an regular error as opposed to a fatal error.
