Implementations

impl<I: Interner> TraitRef<I>

pub fn with_as(&self) -> impl Debug + '_

Returns a "Debuggable" type that prints like P0 as Trait<P1..>

pub fn with_colon(&self) -> impl Debug + '_

Returns a "Debuggable" type that prints like P0: Trait<P1..>

impl<I: Interner> TraitRef<I>

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

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

Trait Implementations

impl<I: Interner> CastTo<TraitRef<I>> for TraitRef<I>

fn cast_to(
    self,
    _interner: &<TraitRef<I> as HasInterner>::Interner
) -> TraitRef<I>

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

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

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

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

Returns a copy of the value.

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

Performs copy-assignment from source.

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

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

Formats the value using the given formatter.

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

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

type Result = TraitRef<_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 TraitRef<I>

type Interner = I

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

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

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

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

This method tests for !=.

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

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

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

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