Trait Implementations

impl<'tcx> FnAbiOfHelpers<'tcx> for Tables<'tcx>

Implement error handling for extracting function ABI information.

type FnAbiOfResult = Result<&'tcx FnAbi<'tcx, Ty<'tcx>>, Error>

The &FnAbi-wrapping type (or &FnAbi itself), which will be returned from fn_abi_of_* (see also handle_fn_abi_err).

fn handle_fn_abi_err( &self, err: FnAbiError<'tcx>, _span: Span, fn_abi_request: FnAbiRequest<'tcx> ) -> Error

Helper used for fn_abi_of_*, to adapt tcx.fn_abi_of_*(...) into a Self::FnAbiOfResult (which does not need to be a Result<...>).

impl<'tcx> HasDataLayout for Tables<'tcx>

fn data_layout(&self) -> &TargetDataLayout

impl<'tcx> HasParamEnv<'tcx> for Tables<'tcx>

fn param_env(&self) -> ParamEnv<'tcx>

impl<'tcx> HasTyCtxt<'tcx> for Tables<'tcx>

fn tcx(&self) -> TyCtxt<'tcx>

impl<'tcx> Index<DefId> for Tables<'tcx>

type Output = DefId

The returned type after indexing.

fn index(&self, index: DefId) -> &Self::Output

Performs the indexing (container[index]) operation.

impl<'tcx> Index<Span> for Tables<'tcx>

type Output = Span

The returned type after indexing.

fn index(&self, index: Span) -> &Self::Output

Performs the indexing (container[index]) operation.

impl<'tcx> LayoutOfHelpers<'tcx> for Tables<'tcx>

type LayoutOfResult = Result<TyAndLayout<'tcx, Ty<'tcx>>, Error>

The TyAndLayout-wrapping type (or TyAndLayout itself), which will be returned from layout_of (see also handle_layout_err).

fn handle_layout_err( &self, err: LayoutError<'tcx>, _span: Span, ty: Ty<'tcx> ) -> Error

Helper used for layout_of, to adapt tcx.layout_of(...) into a Self::LayoutOfResult (which does not need to be a Result<...>).

fn layout_tcx_at_span(&self) -> Span

Span to use for tcx.at(span), from layout_of.

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.
