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.

Trait Implementations

impl Clone for GoalPrec

fn clone(&self) -> GoalPrec

Returns a copy 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<GoalPrec> for GoalPrec

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

This method tests for self and other values to be equal, and is used by ==.

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

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