Struct LRATLiteral

pub struct LRATLiteral(/* private fields */);

A literal in the LRAT proof output

This is essentially this enum, but we pack everything into 32 bits.

enum LRATLiteral {
    ResolutionCandidate(Clause),
    Hint(Clause),
    Zero,
}

Implementations

impl LRATLiteral

pub fn resolution_candidate(clause: Clause) -> LRATLiteral

Create a hint for a resolution candidate.

pub fn is_resolution_candidate(self) -> bool

Return true if this is refers to a resolution candidate.

pub fn hint(clause: Clause) -> LRATLiteral

Create a hint for a unit clause.

pub fn is_hint(self) -> bool

Return true if this is a unit clause hint.

pub fn zero() -> LRATLiteral

Create a zero terminator literal.

pub fn is_zero(self) -> bool

Return true if this is a zero terminator.

pub fn clause(self) -> Clause

Assuming this is not a zero terminator, return the referenced clause.

Trait Implementations

impl Clone for LRATLiteral

fn clone(&self) -> LRATLiteral

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LRATLiteral

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

Formats the value using the given formatter.

impl Default for LRATLiteral

fn default() -> LRATLiteral

Returns the “default value” for a type.

impl Ord for LRATLiteral

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

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for LRATLiteral

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

impl PartialOrd for LRATLiteral

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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