Struct Var 

pub struct Var {
    pub id: VarId,
    pub lb: Option<f64>,
    pub ub: Option<f64>,
    pub is_integer: bool,
    pub is_artificial: bool,
}

Represents a decision variable in a model.

Contains information about optional bounds, whether the variable is integer, and whether it is an artificial variable used in simplex initialization.

Fields

id: VarId

Unique identifier for the variable.

lb: Option<f64>

Optional lower bound.

ub: Option<f64>

Optional upper bound.

is_integer: bool

Whether the variable is restricted to integer values.

is_artificial: bool

Whether this is an artificial variable (used for inequality constraints in simplex initialization).
