Trait Implementations

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

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<I: Interner> Debug for Fn<I>

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

Formats the value using the given formatter.

impl<I: Eq + Interner> Eq for Fn<I>

impl<I: Interner, TI: TargetInterner<I>> Fold<I, TI> for Fn<I>

type Result = Fn<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 Fn<I>

type Interner = I

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

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

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

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

This method tests for !=.

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

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

impl<I: Interner> Visit<I> for Fn<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.
