Struct chalk_ir::ApplicationTy

pub struct ApplicationTy<I: Interner> {
    pub name: TypeName<I>,
    pub substitution: Substitution<I>,
}

Normal Rust types, containing the type name and zero or more generic arguments. For example, in Vec<u32> those would be Vec and [u32] respectively.

Fields

name: TypeName<I>

The type name.

substitution: Substitution<I>

The substitution containing the generic arguments.

Implementations

impl<I: Interner> ApplicationTy<I>

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

Show debug output for the application type.

impl<I: Interner> ApplicationTy<I>

pub fn intern(self, interner: &I) -> Ty<I>

Create an interned type from this application type.

pub fn type_parameters<'a>(
    &'a self,
    interner: &'a I
) -> impl Iterator<Item = Ty<I>> + 'a

Gets an iterator of all type parameters.

pub fn first_type_parameter(&self, interner: &I) -> Option<Ty<I>>

Gets the first type parameter.

pub fn len_type_parameters(&self, interner: &I) -> usize

Gets the number of type parameters.

Trait Implementations

impl<I: Interner> CastTo<TyData<I>> for ApplicationTy<I>

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

Cast a value to type T.

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

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

Returns a copy of the value.

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

Performs copy-assignment from source.

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

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

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

Formats the value using the given formatter.

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

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

type Result = ApplicationTy<_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 ApplicationTy<I>

type Interner = I

The interner associated with the type.

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

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

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

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

This method tests for !=.

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

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

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