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).

Trait Implementations

impl Clone for GoalPrec

fn clone(&self) -> GoalPrec

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for GoalPrec

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for GoalPrec

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for GoalPrec

fn eq(&self, other: &GoalPrec) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
