Enum Const 

pub enum Const {
    Int(i128),
    Float(Float),
    Address(Address),
}

The value of a constant expression, after folding.

Integers are held in a hundred and twenty eight bits whatever their type, which covers every integer type this compiler has including __int128. A _BitInt(N) wider than that is not representable here and is refused where it is written rather than silently truncated.

Variants

Int(i128)

An integer, sign extended into the whole width from the type it has.

Float(Float)

A floating value, in the target’s format rather than the host’s.

Address(Address)

The address of an object, which is a number nobody knows until the link.
