Struct StructLiteral 

pub struct StructLiteral { /* private fields */ }

A straightforward literal representation using a struct.

Stores the variable ID and polarity in separate fields. Less memory-efficient than PackedLiteral if not optimised well by the compiler, but very clear.

Trait Implementations

impl Clone for StructLiteral

fn clone(&self) -> StructLiteral

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StructLiteral

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

Formats the value using the given formatter.

impl Default for StructLiteral

fn default() -> StructLiteral

Returns the “default value” for a type.

impl Hash for StructLiteral

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, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Literal for StructLiteral

fn new(var: Variable, polarity: bool) -> Self

Creates a new literal.

fn variable(self) -> Variable

Returns the Variable identifier of this literal.

fn polarity(self) -> bool

Returns the polarity of this literal.

fn negated(self) -> Self

Returns the negated version of this literal. If self is x_i, returns !x_i. If self is !x_i, returns x_i.

fn is_negated(self) -> bool

Checks if the literal is negated (i.e. has negative polarity). This is equivalent to !self.polarity().

fn is_positive(self) -> bool

Checks if the literal is positive (i.e. has positive polarity). This is equivalent to self.polarity().

fn from_i32(value: i32) -> Self

Creates a literal from an i32 value (DIMACS-style).

fn to_i32(&self) -> i32

Converts the literal to its i32 (DIMACS-style) representation. Positive literal x_v becomes v (as i32). Negative literal !x_v becomes -v (as i32).

fn index(self) -> usize

Converts the literal to a usize index.

fn from_index(index: usize) -> Self

Creates a literal from a usize index. This is the inverse of self.index().

impl Ord for StructLiteral

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

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

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