Implementations

impl<I: Interner> GenericArgData<I>

pub fn inner_debug(&self) -> GenericArgDataInnerDebug<'_, I>

Helper method for debugging GenericArgData.

impl<I: Interner> GenericArgData<I>

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

Create an interned type.

Trait Implementations

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

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

Returns a copy of the value.

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

Performs copy-assignment from source.

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

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

Formats the value using the given formatter.

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

type Result = GenericArgData<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).

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: Hash + Interner> Hash for GenericArgData<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<GenericArgData<I>> for GenericArgData<I>

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

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

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

This method tests for !=.

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

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 GenericArgData<I>

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.

impl<I: Interner> Copy for GenericArgData<I> where
    I::InternedType: Copy,
    I::InternedLifetime: Copy,
    I::InternedConst: Copy, 

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

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

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