Struct Rule 

pub struct Rule {
    pub id: RuleId,
    pub premises: Vec<Literal>,
    pub conclusion: Literal,
    pub kind: RuleKind,
}

A rule: premises → conclusion, either strict or defeasible.

Fields

id: RuleId

Unique rule id within a rule set.

premises: Vec<Literal>

Premises (antecedents).

conclusion: Literal

Conclusion (consequent).

kind: RuleKind

Whether the rule is strict (indefeasible) or defeasible.

Implementations

impl Rule

pub fn strict(id: RuleId, premises: Vec<Literal>, conclusion: Literal) -> Self

Construct a strict rule.

pub fn defeasible( id: RuleId, premises: Vec<Literal>, conclusion: Literal, ) -> Self

Construct a defeasible rule.

pub fn is_defeasible(&self) -> bool

Whether this rule is defeasible.

Trait Implementations

impl Clone for Rule

fn clone(&self) -> Rule

Returns a duplicate 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 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 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.
