The
TyAndLayout
-wrapping type (or TyAndLayout
itself), which will be
returned from layout_of
(see also handle_layout_err
). Read moresourcefn handle_layout_err(&self, err: LayoutError<'tcx>, span: Span, ty: Ty<'tcx>) -> !
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 moresourcefn layout_tcx_at_span(&self) -> Span
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.
