Type Alias ConstValue

pub type ConstValue = ConstValue<Interner>;

Aliased Type

enum ConstValue {
    BoundVar(BoundVar),
    InferenceVar(InferenceVar),
    Placeholder(PlaceholderIndex),
    Concrete(ConcreteConst<Interner>),
}

Variants

BoundVar(BoundVar)

Bound var (e.g. a parameter).

InferenceVar(InferenceVar)

Constant whose value is being inferred.

Placeholder(PlaceholderIndex)

Lifetime on some yet-unknown placeholder.

Concrete(ConcreteConst<Interner>)

Concrete constant value.

Trait Implementations

impl<I> Clone for ConstValue<I>

where I: Clone + Interner,

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<I> HasInterner for ConstValue<I>

where I: Interner,

type Interner = I

The interner associated with the type.

impl<I> Hash for ConstValue<I>

where I: Hash + Interner,

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

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 for ConstValue<I>

where I: PartialEq + Interner,

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl<I> Copy for ConstValue<I>

where I: Interner, <I as Interner>::InternedConcreteConst: Copy,

impl<I> Eq for ConstValue<I>

where I: Eq + Interner,

impl<I> StructuralPartialEq for ConstValue<I>

where I: Interner,
