Struct chalk_ir::AliasEq

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

Proves equality between an alias and a type.

Fields

alias: AliasTy<I>

ty: Ty<I>

Trait Implementations

impl<I: Interner> CastTo<WhereClause<I>> for AliasEq<I>

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

Cast a value to type T.

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

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

Returns a copy of the value.

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

Performs copy-assignment from source.

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

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

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

Formats the value using the given formatter.

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

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

type Result = AliasEq<_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: Interner> HasInterner for AliasEq<I>

type Interner = I

The interner associated with the type.

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

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

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

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

This method tests for !=.

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

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

impl<I: Interner> Visit<I> for AliasEq<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 AliasEq<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.
