Type Alias chalk_ir::CanonicalVarKind

pub type CanonicalVarKind<I: Interner> = WithKind<I, UniverseIndex>;

A variable kind with universe index.

Aliased Type

struct CanonicalVarKind<I: Interner> {
    pub kind: VariableKind<I>,
    pub(crate) value: UniverseIndex,
}

Fields

kind: VariableKind<I>

The associated variable kind.

value: UniverseIndex

The wrapped value.

Implementations

impl<I: Interner, T> WithKind<I, T>

pub fn new(kind: VariableKind<I>, value: T) -> Self

Creates a WithKind from a variable kind and a value.

pub fn map<U, OP>(self, op: OP) -> WithKind<I, U>

where OP: FnOnce(T) -> U,

Maps the value in WithKind.

pub fn map_ref<U, OP>(&self, op: OP) -> WithKind<I, U>

where OP: FnOnce(&T) -> U,

Maps a function taking WithKind<I, &T> over &WithKind<I, T>.

pub fn skip_kind(&self) -> &T

Extract the value, ignoring the variable kind.

Trait Implementations

impl<I: Interner> CastTo<WithKind<I, UniverseIndex>> for CanonicalVarKind<I>

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

Cast a value to type T.

impl<I: Clone + Interner, T: Clone> Clone for WithKind<I, T>

fn clone(&self) -> WithKind<I, T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<I: Interner, T: Debug> Debug for WithKind<I, T>

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

Formats the value using the given formatter.

impl<I: Interner, T> HasInterner for WithKind<I, T>

type Interner = I

The interner associated with the type.

impl<I: Hash + Interner, T: Hash> Hash for WithKind<I, T>

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, T: PartialEq> PartialEq for WithKind<I, T>

fn eq(&self, other: &WithKind<I, T>) -> 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, T: Copy> Copy for WithKind<I, T>

where I::InternedType: Copy,

impl<I: Eq + Interner, T: Eq> Eq for WithKind<I, T>
