Struct rustc_middle::ty::Predicate[][src]

pub struct Predicate<'tcx> {
    inner: &'tcx PredicateInner<'tcx>,


inner: &'tcx PredicateInner<'tcx>


impl<'tcx> Predicate<'tcx>[src]

pub fn kind(self) -> Binder<'tcx, PredicateKind<'tcx>>[src]

Gets the inner Binder<'tcx, PredicateKind<'tcx>>.

impl<'tcx> Predicate<'tcx>[src]

pub fn subst_supertrait(
    tcx: TyCtxt<'tcx>,
    trait_ref: &PolyTraitRef<'tcx>
) -> Predicate<'tcx>

Performs a substitution suitable for going from a poly-trait-ref to supertraits that must hold if that poly-trait-ref holds. This is slightly different from a normal substitution in terms of what happens with bound regions. See lengthy comment below for details.
