Struct LRATDependency

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

An intermediate representation of an LRAT hint

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

enum LRATDependency {
    Unit(Clause),
    ForcedUnit(Clause),
    ResolutionCandidate(Clause),
}

Implementations

impl LRATDependency

pub fn unit_in_inference(clause: Clause) -> LRATDependency

Create a hint stating that the given clause became unit during the redundancy check.

pub fn is_unit_in_inference(self) -> bool

Return true if this was a unit in the inference check.

pub fn forced_unit(clause: Clause) -> LRATDependency

Create a hint stating that the given clause was unit even before the redundancy check.

pub fn is_forced_unit(self) -> bool

Return true if this is a hint for a forced unit clause.

pub fn resolution_candidate(clause: Clause) -> LRATDependency

Create a hint referring to the given clause as resolution candidate.

pub fn is_resolution_candidate(self) -> bool

Return true if this is a hint for a resolution candidate.

pub fn clause(self) -> Clause

Return the clause referenced by this hint.

Trait Implementations

impl Clone for LRATDependency

fn clone(&self) -> LRATDependency

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LRATDependency

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

Formats the value using the given formatter.

impl Default for LRATDependency

fn default() -> LRATDependency

Returns the “default value” for a type.

impl Ord for LRATDependency

fn cmp(&self, other: &LRATDependency) -> 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 LRATDependency

fn eq(&self, other: &LRATDependency) -> 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 LRATDependency

fn partial_cmp(&self, other: &LRATDependency) -> 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.
