Represents the bounds for an impl Trait type.
ⓘThis example is not tested
opaque type T: A + B = HiddenTy;
Fields
opaque_ty_id: OpaqueTyId<I>The placeholder !T that corresponds to the opaque type T.
bound: Binders<OpaqueTyDatumBound<I>>The type bound to when revealed.

impl<I: Interner, _TI> Fold<I, _TI> for OpaqueTyDatum<I> where
_TI: TargetInterner<I>, [src]
_TI: TargetInterner<I>,
type Result = OpaqueTyDatum<_TI>
The type of value that will be produced once folding is done.
Typically this is Self, unless Self contains borrowed
values, in which case owned values are produced (for example,
one can fold over a &T value where T: Fold, in which case
you get back a T, not a &T). Read more

Given opaque type T<U>: A + B = HiddenTy where U: C;, we generate:
AliasEq(T<U> = HiddenTy) :- Reveal.
AliasEq(T<U> = !T<U>).
WF(T<U>) :- WF(U: C).
Implemented(!T<U>: A).
Implemented(!T<U>: B).
where !T<..> is the placeholder for the unnormalized type T<..>.
