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<...>). Read moresource§type LayoutOfResult = TyAndLayout<'tcx, Ty<'tcx>>
type LayoutOfResult = TyAndLayout<'tcx, Ty<'tcx>>
The
TyAndLayout-wrapping type (or TyAndLayout itself), which will be
returned from layout_of (see also handle_layout_err).source§fn layout_tcx_at_span(&self) -> Span
fn layout_tcx_at_span(&self) -> Span

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.
