Struct ThresholdConstraintOver 

pub(crate) struct ThresholdConstraintOver<T> {
    variable: T,
    thr_constr: ThresholdConstraint,
}

This struct represents a Threshold constraint over an object of type T

It is used to, for example, represent a threshold guard over a variable

Fields

variable: T

thr_constr: ThresholdConstraint

Implementations

impl<T> ThresholdConstraintOver<T>

pub fn new(variable: T, thr_constr: ThresholdConstraint) -> Self

Create a new symbolic constraint over an object of type T

pub fn is_upper_guard(&self) -> bool

Check whether the constraint is an upper guard

An upper guard is a guard of the form < t or <= t or != t or == t, as it can become disabled when the threshold is reached.

pub fn is_lower_guard(&self) -> bool

Check whether the constraint is a lower guard

A lower guard is a guard of the form > t or >= t or != t or == t, as it can become enabled when the threshold is reached.

pub fn get_variable(&self) -> &T

Get the subject of the constraint

pub fn get_threshold(&self) -> &Threshold

Get the threshold of the constraint

pub fn get_threshold_constraint(&self) -> &ThresholdConstraint

Get the threshold constraint of this constraint

pub fn encode_to_boolean_expr<S>(&self) -> BooleanExpression<S>

where S: Atomic, T: IntoNoDivBooleanExpr<S>, Threshold: IntoNoDivBooleanExpr<S>,

Encode the constraint into a BooleanExpression

This encoding will be guaranteed to not include rational constants

Trait Implementations

impl<T: Clone> Clone for ThresholdConstraintOver<T>

fn clone(&self) -> ThresholdConstraintOver<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for ThresholdConstraintOver<T>

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

Formats the value using the given formatter.

impl<T> Display for ThresholdConstraintOver<T>

where T: Display,

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

Formats the value using the given formatter.

impl<S, T> From<ThresholdConstraintOver<T>> for BooleanExpression<S>

where S: Atomic, T: IntoNoDivBooleanExpr<S>, Threshold: IntoNoDivBooleanExpr<S>,

fn from(val: ThresholdConstraintOver<T>) -> Self

Converts to this type from the input type.

impl<T: Hash> Hash for ThresholdConstraintOver<T>

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<T: Ord> Ord for ThresholdConstraintOver<T>

fn cmp(&self, other: &ThresholdConstraintOver<T>) -> 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<T: PartialEq> PartialEq for ThresholdConstraintOver<T>

fn eq(&self, other: &ThresholdConstraintOver<T>) -> 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<T: PartialOrd> PartialOrd for ThresholdConstraintOver<T>

fn partial_cmp(&self, other: &ThresholdConstraintOver<T>) -> 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.
