Trait Implementations

impl<'tcx> TypeOpInfo<'tcx> for PredicateQuery<'tcx>

fn fallback_error(&self, tcx: TyCtxt<'tcx>, span: Span) -> Diag<'tcx>

Returns an error to be reported if rerunning the type op fails to recover the error’s cause.

fn base_universe(&self) -> UniverseIndex

fn nice_error<'infcx>( &self, mbcx: &mut MirBorrowckCtxt<'_, '_, 'infcx, 'tcx>, cause: ObligationCause<'tcx>, placeholder_region: Region<'tcx>, error_region: Option<Region<'tcx>>, ) -> Option<Diag<'infcx>>

fn report_error( &self, mbcx: &mut MirBorrowckCtxt<'_, '_, '_, 'tcx>, placeholder: PlaceholderRegion, error_element: RegionElement, cause: ObligationCause<'tcx>, )

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
