pub struct Normalize<I: Interner> {
    pub alias: AliasTy<I>,
    pub ty: Ty<I>,
}

Expand description

Proves that the given type alias normalizes to the given type. A projection T::Foo normalizes to the type U if we can match it to an impl and that impl has a type Foo = V where U = V.

impl<I: Interner> Fold for Normalize

type Result = Normalize

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

fn fold_with<E>(
 self,
 folder: &mut dyn Folder<I, Error = E>,
 outer_binder: DebruijnIndex
) -> Result<Self::Result, E>

Apply the given folder folder to self; binders is the number of binders that are in scope when beginning the folder. Typically binders starts as 0, but is adjusted when we encounter Binders<T> in the IR or other similar constructs. Read more
