Enum z3_sys::GoalPrec

#[repr(u32)]
pub enum GoalPrec {
    Precise,
    Under,
    Over,
    UnderOver,
}

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.

This corresponds to Z3_goal_prec in the C API.

Variants

Precise

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

This corresponds to Z3_GOAL_PRECISE in the C API.

Under

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

This corresponds to Z3_GOAL_UNDER in the C API.

Over

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

This corresponds to Z3_GOAL_OVER in the C API.

UnderOver

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

This corresponds to Z3_GOAL_UNDER_OVER in the C API.
