Struct good_lp::variable::Variable

pub struct Variable { /* fields omitted */ }

A variable in a problem. Use variables to create expressions, to express the objective and the Constraints of your model.

Variables are created using ProblemVariables::add

Warning

Eq is implemented on this type, but v1 == v2 is true only if the two variables represent the same object, not if they have the same definition.

let mut vars = variables!();
let v1 = vars.add(variable().min(1).max(8));
let v2 = vars.add(variable().min(1).max(8));
assert_ne!(v1, v2);

let v1_copy = v1;
assert_eq!(v1, v1_copy);
