Enum ConstantKind 

pub enum ConstantKind {
    Ty(TyConst),
    Allocated(Allocation),
    Unevaluated(UnevaluatedConst),
    Param(ParamConst),
    ZeroSized,
}

Variants

Ty(TyConst)

Allocated(Allocation)

Unevaluated(UnevaluatedConst)

Param(ParamConst)

ZeroSized

Store ZST constants. We have to special handle these constants since its type might be generic.

Trait Implementations

impl Clone for ConstantKind

fn clone(&self) -> ConstantKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ConstantKind

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

Formats the value using the given formatter.

impl Hash for ConstantKind

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 PartialEq for ConstantKind

fn eq(&self, other: &ConstantKind) -> 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 Serialize for ConstantKind

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for ConstantKind

impl StructuralPartialEq for ConstantKind

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
