Struct Address 

pub struct Address {
    pub base: Base,
    pub offset: i128,
}

An address constant: some object, and how far into it.

This is what &x, a + 1 and &s.field fold to, and it is the reason folding hands back something richer than a number. The value is not known here and will not be known until the linker places the object, so what a static initializer needs is not the value but the pair that names it, which is what an object file’s relocation records.

A pointer with no object behind it is not one of these. (int *)4 folds to Const::Int, because four is the whole answer and nothing has to be relocated.

Fields

base: Base

The object the address is into.

offset: i128

How many bytes into it, which a member or a subscript adds to and which may be outside the object: &a[10] on an int a[10] is a valid address constant and is one past it.
