Struct Rel 

pub struct Rel(pub String);

Relations are semantic counterparts of predicates and are used to store Facts in models.

Note: Rel is the counterpart of Pred at a semantic level.

Tuple Fields

Implementations

impl Rel

pub fn app<T: WitnessTermTrait>(self, terms: Vec<T>) -> Observation<T>

Applies the receiver to a list of witness terms.

pub fn app0<T: WitnessTermTrait>(self) -> Observation<T>

Applies the (nullary) receiver.

pub fn app1<T: WitnessTermTrait>(self, first: T) -> Observation<T>

Applies the (unary) receiver on a witness term.

pub fn app2<T: WitnessTermTrait>(self, first: T, second: T) -> Observation<T>

Applies the (binary) receiver on two witness terms.

pub fn app3<T: WitnessTermTrait>( self, first: T, second: T, third: T, ) -> Observation<T>

Applies the (ternary) receiver on three witness terms.

pub fn app4<T: WitnessTermTrait>( self, first: T, second: T, third: T, fourth: T, ) -> Observation<T>

Applies the (4-ary) receiver on four witness terms.

pub fn app5<T: WitnessTermTrait>( self, first: T, second: T, third: T, fourth: T, fifth: T, ) -> Observation<T>

Applies the (5-ary) receiver on five witness terms.

Trait Implementations

impl Clone for Rel

fn clone(&self) -> Rel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Rel

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

Formats the value using the given formatter.

impl Display for Rel

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

Formats the value using the given formatter.

impl From<&str> for Rel

fn from(s: &str) -> Self

Converts to this type from the input type.

impl From<Pred> for Rel

fn from(predicate: Pred) -> Self

Converts to this type from the input type.

impl From<String> for Rel

fn from(s: String) -> Self

Converts to this type from the input type.

impl Hash for Rel

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 Ord for Rel

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

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

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

impl Eq for Rel
