Struct chalk_ir::Normalize

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

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.

Fields

alias: AliasTy<I>

ty: Ty<I>

Trait Implementations

impl<I: Interner> CastTo<DomainGoal<I>> for Normalize<I>

fn cast_to(self, _interner: &I) -> DomainGoal<I>

Cast a value to type T.

impl<I: Clone + Interner> Clone for Normalize<I>

fn clone(&self) -> Normalize<I>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<I: Interner> Copy for Normalize<I> where
    I::InternedSubstitution: Copy,
    I::InternedType: Copy, 

impl<I: Interner> Debug for Normalize<I>

fn fmt(&self, fmt: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<I: Eq + Interner> Eq for Normalize<I>

impl<I: Interner, _TI> Fold<I, _TI> for Normalize<I> where
    _TI: TargetInterner<I>, 

type Result = Normalize<_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).

fn fold_with<'i>(
    &self,
    folder: &mut dyn Folder<'i, I, _TI>,
    outer_binder: DebruijnIndex
) -> Fallible<Self::Result> where
    I: 'i,
    _TI: 'i, 

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.

impl<I: Hash + Interner> Hash for Normalize<I>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given [Hasher].

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given [Hasher].

impl<I: PartialEq + Interner> PartialEq<Normalize<I>> for Normalize<I>

fn eq(&self, other: &Normalize<I>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Normalize<I>) -> bool

This method tests for !=.

impl<I: Interner> StructuralEq for Normalize<I>

impl<I: Interner> StructuralPartialEq for Normalize<I>

impl<I: Interner> Visit<I> for Normalize<I>

fn visit_with<'i, R: VisitResult>(
    &self,
    visitor: &mut dyn Visitor<'i, I, Result = R>,
    outer_binder: DebruijnIndex
) -> R where
    I: 'i, 

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

impl<I: Interner> Zip<I> for Normalize<I>

fn zip_with<'i, Z: Zipper<'i, I>>(
    zipper: &mut Z,
    a: &Self,
    b: &Self
) -> Fallible<()> where
    I: 'i, 

Uses the zipper to walk through two values, ensuring that they match.
