Enum Value

pub enum Value {
    Number(Number),
    Expr(Expr),
}

A dynamically or statically computed value.

To produce valid binary it is mostly only important to know the correct width of the output but the value itself can be computed by the caller. This allows freedom on parsing without requiring the assembler core (this library) to implement an arbitrary expression evaluator. In particular, the evaluation can even be further delayed by the caller and left to rustc.

Variants

Number(Number)

A constant number.

Expr(Expr)

An external expression of the caller.
