Trait Implementations

impl<'tcx> Clone for layout_of<'tcx>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'tcx> Default for layout_of<'tcx>

fn default() -> layout_of<'tcx>

Returns the “default value” for a type.

impl<'tcx> QueryConfigRestored<'tcx> for layout_of<'tcx>

type RestoredValue = Result<TyAndLayout<'tcx, Ty<'tcx>>, LayoutError<'tcx>>

type Config = DynamicConfig<'tcx, DefaultCache<ParamEnvAnd<'tcx, Ty<'tcx>>, Erased<impl Copy>>, false, true, false>

fn config(tcx: TyCtxt<'tcx>) -> Self::Config

fn restore(value: Erased<impl Copy>) -> Self::RestoredValue

impl<'tcx> Copy for layout_of<'tcx>

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.
