Trait Implementations

impl<'tcx> Clone for LayoutCx<'tcx>

fn clone(&self) -> LayoutCx<'tcx>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'tcx> HasDataLayout for LayoutCx<'tcx>

fn data_layout(&self) -> &TargetDataLayout

impl<'tcx> HasParamEnv<'tcx> for LayoutCx<'tcx>

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

impl<'tcx> HasTargetSpec for LayoutCx<'tcx>

fn target_spec(&self) -> &Target

impl<'tcx> HasTyCtxt<'tcx> for LayoutCx<'tcx>

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

impl<'tcx> HasWasmCAbiOpt for LayoutCx<'tcx>

fn wasm_c_abi_opt(&self) -> WasmCAbi

impl<'tcx> LayoutOfHelpers<'tcx> for LayoutCx<'tcx>

type LayoutOfResult = Result<TyAndLayout<'tcx, Ty<'tcx>>, &'tcx LayoutError<'tcx>>

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, _: Ty<'tcx>, ) -> &'tcx LayoutError<'tcx>

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.
