§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 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<...>). Read moresource§fn layout_tcx_at_span(&self) -> Span
fn layout_tcx_at_span(&self) -> Span
Span to use for tcx.at(span), from layout_of.Auto Trait Implementations§

source§fn layout_of(&self, ty: Ty<'tcx>) -> Self::LayoutOfResult
fn layout_of(&self, ty: Ty<'tcx>) -> Self::LayoutOfResult
Computes the layout of a type. Note that this implicitly
executes in “reveal all” mode, and will normalize the input type.
source§fn spanned_layout_of(&self, ty: Ty<'tcx>, span: Span) -> Self::LayoutOfResult
fn spanned_layout_of(&self, ty: Ty<'tcx>, span: Span) -> Self::LayoutOfResult
Computes the layout of a type, at
span. Note that this implicitly
executes in “reveal all” mode, and will normalize the input type.source§impl<T> MaybeResult<T> for T

fn truncate_to_ptr(&self, _: (u64, bool)) -> (u64, bool)
Helper function: truncate given value-“overflowed flag” pair to pointer size and
update “overflowed flag” if there was an overflow.
This should be called by all the other methods before returning!

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.
