Trait Implementations

impl<'tcx> TypeRelation<'tcx> for SameTypeModuloInfer<'_, 'tcx>

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

fn tag(&self) -> &'static str

Returns a static string we can use for printouts.

fn relate_with_variance<T: Relate<'tcx>>( &mut self, _variance: Variance, _info: VarianceDiagInfo<'tcx>, a: T, b: T ) -> RelateResult<'tcx, T>

Switch variance for the purpose of relating a and b.

fn tys(&mut self, a: Ty<'tcx>, b: Ty<'tcx>) -> RelateResult<'tcx, Ty<'tcx>>

fn regions( &mut self, a: Region<'tcx>, b: Region<'tcx> ) -> RelateResult<'tcx, Region<'tcx>>

fn binders<T>( &mut self, a: Binder<'tcx, T>, b: Binder<'tcx, T> ) -> RelateResult<'tcx, Binder<'tcx, T>>

where T: Relate<'tcx>,

fn consts( &mut self, a: Const<'tcx>, _b: Const<'tcx> ) -> RelateResult<'tcx, Const<'tcx>>

fn relate<T>(&mut self, a: T, b: T) -> Result<T, TypeError<'tcx>>

where T: Relate<'tcx>,

Generic relation routine suitable for most anything.

fn relate_item_args( &mut self, item_def_id: DefId, a_arg: &'tcx RawList<(), GenericArg<'tcx>>, b_arg: &'tcx RawList<(), GenericArg<'tcx>> ) -> Result<&'tcx RawList<(), GenericArg<'tcx>>, TypeError<'tcx>>

Relate the two args for the given item. The default is to look up the variance for the item and proceed accordingly.

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.
