Implementations

impl Lit

pub const UNDEF: Lit

pub const ERROR: Lit

pub fn new(var: Var, sign: bool) -> Self

pub fn idx(&self) -> u32

pub fn sign(&self) -> bool

pub fn var(&self) -> Var

pub fn apply_sign(&self, sign: bool) -> Lit

lit.apply_sign(b) keeps the same sign if b==true, flips sign otherwise

use batsat::*;

assert_eq!(lit1, lit1.apply_sign(true));
assert_eq!(!lit1, lit1.apply_sign(false));
let lit2 = Lit::new(sat.new_var_default(), false);
