Enum Constant 

pub enum Constant {
    Int(Int),
    Bool(bool),
    GlobalPointer(Relocation),
    FnPointer(FnName),
    VTablePointer(VTableName),
    PointerWithoutProvenance(Int),
}

Constants are basically values, but cannot have explicit provenance. Currently we do not support Ptr and Union constants.

Variants

Int(Int)

A mathematical integer, used for i*/u* types.

Bool(bool)

A Boolean value, used for bool.

GlobalPointer(Relocation)

A pointer pointing into a global allocation with a given offset.

FnPointer(FnName)

A pointer pointing to a function.

VTablePointer(VTableName)

A pointer pointing to a vtable.

PointerWithoutProvenance(Int)

A pointer with constant address, not pointing into any allocation.

impl Ord for Constant

fn cmp(&self, other: &Constant) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for Constant

fn eq(&self, other: &Constant) -> bool

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Constant

fn partial_cmp(&self, other: &Constant) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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