Enum IntervalConstraint 

pub enum IntervalConstraint {
    True,
    False,
    Conj(Box<IntervalConstraint>, Box<IntervalConstraint>),
    Disj(Box<IntervalConstraint>, Box<IntervalConstraint>),
    SingleVarIntervalConstr(Variable, Vec<Interval>),
    MultiVarIntervalConstr(WeightedSum<Variable>, Vec<Interval>),
}

Interval guard constraining the interval of evaluation of a variable or a sum of variables

Variants

True

Guard is always enabled

False

Guard is always disabled

Conj(Box<IntervalConstraint>, Box<IntervalConstraint>)

Conjunction of interval guard

Disj(Box<IntervalConstraint>, Box<IntervalConstraint>)

Disjunction of interval guard

SingleVarIntervalConstr(Variable, Vec<Interval>)

Interval guard over a single variable

The guard is enabled if the variable is in one of the intervals.

MultiVarIntervalConstr(WeightedSum<Variable>, Vec<Interval>)

Interval guard over a sum of variables

The guard is enabled if the sum of variables is in one of the intervals.

Implementations

impl IntervalConstraint

pub fn is_enabled( &self, state: &IntervalState<Variable>, ) -> Result<bool, IntervalOrderError<Variable>>

Check if the guard is enabled in the given state

pub(crate) fn from_lia_constr<S: IntervalOrderFor<Variable> + IntervalOrderFor<WeightedSum<Variable>>>( guard: &LIAVariableConstraint, order: &S, ) -> Result<Self, IntervalConstraintConstructionError>

Derive an interval guard from a guard of a linear integer arithmetic guard under the current interval order

pub(crate) fn get_enabled_intervals<'a>( &'a self, var: &Variable, intervals_of_var: Vec<&'a Interval>, ) -> Vec<&'a Interval>

Get the the set of intervals for which the constraint self is satisfied for variable var

This function requires intervals_of_var to be the set of all intervals for var in the automaton. (Which can be obtained from the interval order)

Trait Implementations

impl Clone for IntervalConstraint

fn clone(&self) -> IntervalConstraint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IntervalConstraint

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

Formats the value using the given formatter.

impl Display for IntervalConstraint

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

Formats the value using the given formatter.

impl Hash for IntervalConstraint

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 IntervalConstraint

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

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

fn partial_cmp(&self, other: &IntervalConstraint) -> 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 VariableConstraint for IntervalConstraint

fn as_boolean_expr(&self) -> BooleanExpression<Variable>

Get the guard as a boolean expression over variables

impl Eq for IntervalConstraint

impl StructuralPartialEq for IntervalConstraint
