Required Methods

fn build_overflow_error<T>( &self, predicate: &T, span: Span, suggest_increasing_limit: bool ) -> DiagnosticBuilder<'tcx>

where T: Display + TypeFoldable<TyCtxt<'tcx>> + Print<'tcx, FmtPrinter<'tcx, 'tcx>>,

fn report_overflow_error<T>( &self, predicate: &T, span: Span, suggest_increasing_limit: bool, mutate: impl FnOnce(&mut Diagnostic) ) -> !

where T: Display + TypeFoldable<TyCtxt<'tcx>> + Print<'tcx, FmtPrinter<'tcx, 'tcx>>,

fn report_overflow_no_abort( &self, obligation: PredicateObligation<'tcx> ) -> ErrorGuaranteed

fn report_fulfillment_errors( &self, errors: Vec<FulfillmentError<'tcx>> ) -> ErrorGuaranteed

fn report_overflow_obligation<T>( &self, obligation: &Obligation<'tcx, T>, suggest_increasing_limit: bool ) -> !

where T: ToPredicate<'tcx> + Clone,

fn suggest_new_overflow_limit(&self, err: &mut Diagnostic)

fn report_overflow_obligation_cycle( &self, cycle: &[PredicateObligation<'tcx>] ) -> !

fn report_selection_error( &self, obligation: PredicateObligation<'tcx>, root_obligation: &PredicateObligation<'tcx>, error: &SelectionError<'tcx> )

The root_obligation parameter should be the root_obligation field from a FulfillmentError. If no FulfillmentError is available, then it should be the same as obligation.

fn emit_specialized_closure_kind_error( &self, obligation: &PredicateObligation<'tcx>, trait_ref: PolyTraitRef<'tcx> ) -> Option<ErrorGuaranteed>

fn fn_arg_obligation(&self, obligation: &PredicateObligation<'tcx>) -> bool

fn try_conversion_context( &self, obligation: &PredicateObligation<'tcx>, trait_ref: TraitRef<'tcx>, err: &mut Diagnostic ) -> bool

fn report_const_param_not_wf( &self, ty: Ty<'tcx>, obligation: &PredicateObligation<'tcx> ) -> DiagnosticBuilder<'tcx>
