Struct chalk_ir::OpaqueTy

pub struct OpaqueTy<I: Interner> {
    pub opaque_ty_id: OpaqueTyId<I>,
    pub substitution: Substitution<I>,
}

An opaque type opaque type T<..>: Trait = HiddenTy.

Fields

opaque_ty_id: OpaqueTyId<I>

The id for the opaque type.

substitution: Substitution<I>

The substitution for the opaque type.

Implementations

impl<I: Interner> OpaqueTy<I>

pub fn debug<'a>(&'a self, interner: &'a I) -> OpaqueTyDebug<'a, I>

Show debug output for the opaque type.

Trait Implementations

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

pub fn clone(&self) -> OpaqueTy<I>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<I: Interner> Copy for OpaqueTy<I> where
    I::InternedSubstitution: Copy, 

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

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

Formats the value using the given formatter.

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

impl<I: Interner> Fold<I> for OpaqueTy<I>

type Result = OpaqueTy<I>

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).

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

type Interner = I

The interner associated with the type.

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

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

Feeds this value into the given Hasher.

pub 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<OpaqueTy<I>> for OpaqueTy<I>

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

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

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

This method tests for !=.

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

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

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

pub fn visit_with<'i, B>(
    &self,
    visitor: &mut dyn Visitor<'i, I, BreakTy = B>,
    outer_binder: DebruijnIndex
) -> ControlFlow<B> 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 OpaqueTy<I>

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

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