Trait Implementations

impl<'tcx> HasDataLayout for UnwrapLayoutCx<'tcx>

fn data_layout(&self) -> &TargetDataLayout

impl<'tcx> HasParamEnv<'tcx> for UnwrapLayoutCx<'tcx>

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

impl<'tcx> HasTyCtxt<'tcx> for UnwrapLayoutCx<'tcx>

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

impl<'tcx> LayoutOfHelpers<'tcx> for UnwrapLayoutCx<'tcx>

type LayoutOfResult = TyAndLayout<'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: Span,
    ty: Ty<'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.
