Enum ConstantValue 

pub enum ConstantValue {
    Int(i64),
    Float(f64),
    UInt(u64),
    Bool(bool),
}

The scalars are stored with the highest precision possible, but they might get reduced during compilation. For constant propagation, casts are always executed before converting back to the larger type to ensure deterministic output.

Variants

Int(i64)

Float(f64)

UInt(u64)

Bool(bool)
