Struct Clause 

pub struct Clause {
    pub literals: Vec<Literal>,
}

A clause: a disjunction of literals.

Fields

literals: Vec<Literal>

The literals in the clause.

Implementations

impl Clause

pub fn empty() -> Self

Create an empty clause (represents ⊥).

pub fn new(literals: Vec<Literal>) -> Self

Create a clause from a list of literals.

pub fn is_empty_clause(&self) -> bool

Returns true if this is the empty clause (contradiction).

pub fn is_tautology(&self) -> bool

Returns true if the clause is a tautology (contains x and ¬x).

pub fn is_unit(&self) -> bool

Returns true if the clause is a unit clause (exactly one literal).

Trait Implementations

impl Clone for Clause

fn clone(&self) -> Clause

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Clause

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

Formats the value using the given formatter.

impl PartialEq for Clause

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