Type Alias rustc_middle::ty::PolyProjectionPredicate

pub type PolyProjectionPredicate<'tcx> = Binder<'tcx, ProjectionPredicate<'tcx>>;

Aliased Type

struct PolyProjectionPredicate<'tcx> {
    value: ProjectionPredicate<'tcx>,
    bound_vars: &'tcx List<BoundVariableKind>,
}

Fields

value: ProjectionPredicate<'tcx>

bound_vars: &'tcx List<BoundVariableKind>

Implementations

impl<'tcx> PolyProjectionPredicate<'tcx>

pub fn trait_def_id(&self, tcx: TyCtxt<'tcx>) -> DefId

Returns the DefId of the trait of the associated item being projected.

pub fn required_poly_trait_ref(&self, tcx: TyCtxt<'tcx>) -> PolyTraitRef<'tcx>

Get the PolyTraitRef required for this projection to be well formed. Note that for generic associated types the predicates of the associated type also need to be checked.

pub fn term(&self) -> Binder<'tcx, Term<'tcx>>

pub fn projection_def_id(&self) -> DefId

The DefId of the TraitItem for the associated type.

Note that this is not the DefId of the TraitRef containing this associated type, which is in tcx.associated_item(projection_def_id()).container.

Trait Implementations

impl<'tcx> ToPredicate<'tcx, Clause<'tcx>> for PolyProjectionPredicate<'tcx>

impl<'tcx> ToPredicate<'tcx, Predicate<'tcx>> for PolyProjectionPredicate<'tcx>

fn to_predicate(self, tcx: TyCtxt<'tcx>) -> Predicate<'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.
