Struct gurobi::LinExpr

pub struct LinExpr {
    // some fields omitted
}

Linear expression of variables

A linear expression consists of a constant term plus a list of coefficients and variables.

Methods

impl LinExpr

fn new() -> Self

Create an empty linear expression.

fn add_term(self, coeff: f64, var: Var) -> Self

Add a linear term into the expression.

fn add_constant(self, constant: f64) -> Self

Add a constant into the expression.

fn get_value(&self, model: &Model) -> Result<f64>

Get actual value of the expression.
