pub struct Lit {
    pub var: usize,
    pub pos: bool,
}

A literal: variable var, positive when pos.

Implementations

impl Lit

pub fn pos(var: usize) -> Self

Positive literal x.

pub fn neg(var: usize) -> Self

Negative literal ¬x.

Trait Implementations

impl Clone for Lit

fn clone(&self) -> Lit

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Lit

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

Formats the value using the given formatter.

impl PartialEq for Lit

fn eq(&self, other: &Lit) -> 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.
