Struct EpistemicAssumption 

pub struct EpistemicAssumption {
    pub kind: EpistemicAssumptionKind,
    pub predicate: String,
    pub arity: usize,
    pub terms: Vec<EpistemicEvidenceTerm>,
    pub value: bool,
}

One bounded epistemic assumption compiled as evidence.

Fields

kind: EpistemicAssumptionKind

Assumption kind.

predicate: String

Predicate name.

arity: usize

Predicate arity.

terms: Vec<EpistemicEvidenceTerm>

Concrete tuple terms for nonzero-arity evidence conditioning.

value: bool

Assumed evidence truth value.

Implementations

impl EpistemicAssumption

pub fn known(predicate: impl Into<String>, arity: usize, value: bool) -> Self

Construct a know predicate/arity = value assumption.

pub fn known_tuple( predicate: impl Into<String>, terms: Vec<EpistemicEvidenceTerm>, value: bool, ) -> Self

Construct a know predicate(terms...) = value assumption.

pub fn possible(predicate: impl Into<String>, arity: usize, value: bool) -> Self

Construct a possible predicate/arity = value assumption.

pub fn possible_tuple( predicate: impl Into<String>, terms: Vec<EpistemicEvidenceTerm>, value: bool, ) -> Self

Construct a possible predicate(terms...) = value assumption.

pub fn evidence_literal(&self) -> String

Return the compiler-facing evidence literal for this assumption.

Trait Implementations

impl Clone for EpistemicAssumption

fn clone(&self) -> EpistemicAssumption

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EpistemicAssumption

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

Formats the value using the given formatter.

impl Ord for EpistemicAssumption

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

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

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