Implementations

impl<I: Interner> VariableKind<I>

pub(crate) fn to_bound_variable( &self, interner: I, bound_var: BoundVar ) -> GenericArg<I>

Trait Implementations

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

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

Cast a value to type T.

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

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

Returns a copy of the value.

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

Performs copy-assignment from source.

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

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

Formats the value using the given formatter.

impl<I: Interner> HasInterner for VariableKind<I>

type Interner = I

The interner associated with the type.

impl<I: Hash + Interner> Hash for VariableKind<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, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<I: PartialEq + Interner> PartialEq for VariableKind<I>

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

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

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<I: Interner> Zip<I> for VariableKind<I>

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

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

impl<I: Interner> Copy for VariableKind<I>

where I::InternedType: Copy,

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

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