Struct Rule

pub struct Rule {
    pub head: Sentence,
    pub body: Vec<Literal>,
}

A GDL rule contains a head Sentence that is implied by all the Literals in the body

Fields

head: Sentence

body: Vec<Literal>

Implementations

impl Rule

pub fn new(head: Sentence, body: Vec<Literal>) -> Rule

Trait Implementations

impl Clone for Rule

fn clone(&self) -> Rule

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Rule

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

Formats the value using the given formatter.

impl Decodable for Rule

fn decode<__D: Decoder>(d: &mut __D) -> Result<Rule, __D::Error>

Deserialize a value using a Decoder.

impl Display for Rule

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

Formats the value using the given formatter.

impl Encodable for Rule

fn encode<__S: Encoder>(&self, s: &mut __S) -> Result<(), __S::Error>

Serialize a value using an Encoder.

impl Hash for Rule

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 Into<Clause> for Rule

fn into(self) -> Clause

Converts this type into the (usually inferred) input type.

impl Into<Rule> for Sentence

fn into(self) -> Rule

Converts this type into the (usually inferred) input type.

impl Ord for Rule

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

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

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