Enum GoalPrec 

#[repr(u32)]
pub enum GoalPrec {
    Precise = 0,
    Under = 1,
    Over = 2,
    UnderOver = 3,
}

A Goal is essentially a set of formulas. Z3 provide APIs for building strategies/tactics for solving and transforming Goals. Some of these transformations apply under/over approximations.

Variants

Precise = 0

Approximations/Relaxations were not applied on the goal (sat and unsat answers were preserved).

Under = 1

Goal is the product of a under-approximation (sat answers are preserved).

Over = 2

Goal is the product of an over-approximation (unsat answers are preserved).

UnderOver = 3

Goal is garbage (it is the product of over- and under-approximations, sat and unsat answers are not preserved).
