Struct cnf_parser::Literal

pub struct Literal { /* fields omitted */ }

A clause literal.

Implementations

impl Literal

pub fn is_positive(self) -> bool

Returns true if the literal is positive.

pub fn is_negative(self) -> bool

Returns true if the literal is negative.

pub fn variable(self) -> NonZeroU32

Returns the variable ID of the literal.

pub fn into_value(self) -> NonZeroI32

Returns the raw value representation of the literal.

Trait Implementations

impl Clone for Literal

fn clone(&self) -> Literal

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for Literal

impl Debug for Literal

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

Formats the value using the given formatter.

impl Eq for Literal

impl Hash for Literal

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, 

Feeds a slice of this type into the given [Hasher].

impl Ord for Literal

fn cmp(&self, other: &Literal) -> Ordering

This method returns an [Ordering] between self and other.

#[must_use]fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]fn clamp(self, min: Self, max: Self) -> Self

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl PartialEq<Literal> for Literal

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

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

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

This method tests for !=.

impl PartialOrd<Literal> for Literal

fn partial_cmp(&self, other: &Literal) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Literal) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Literal) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Literal) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Literal) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
