Struct Variable 

pub struct Variable<Identifier = String> {
    pub ty: Type,
    pub domain: Option<Domain>,
    pub value: Option<Literal<Identifier>>,
    pub ann: Vec<Annotation<Identifier>>,
    pub defined: bool,
    pub introduced: bool,
}

The definition of a decision variable

Fields

ty: Type

The type of the decision variable

domain: Option<Domain>

The set of potential values from which the decision variable must take its value in a solution

If domain has the value None, then all values of the decision variable’s Type are allowed in a solution.

value: Option<Literal<Identifier>>

The “right hand side” of the variable, i.e., its value or alias to another variable

ann: Vec<Annotation<Identifier>>

A list of annotations

defined: bool

This field is set to true when there is a constraint that has been marked as defining this variable.

introduced: bool

This field is set to true when the variable has been introduced by the MiniZinc compiler, rather than being explicitly defined at the top-level of the MiniZinc model.

Trait Implementations

impl<Identifier: Clone> Clone for Variable<Identifier>

fn clone(&self) -> Variable<Identifier>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<Identifier: Debug> Debug for Variable<Identifier>

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

Formats the value using the given formatter.

impl<'de, Identifier> Deserialize<'de> for Variable<Identifier>

where Identifier: Deserialize<'de> + Default,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<Identifier: PartialEq> PartialEq for Variable<Identifier>

fn eq(&self, other: &Variable<Identifier>) -> 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<Identifier> Serialize for Variable<Identifier>

where Identifier: Serialize,

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
