Algebraic modeling API for otspot.

Provides [Model], [Variable], [Expression], [Constraint], the [constraint!] macro, and associated error/result types.

Example

use otspot_model::{Model, constraint};

let mut model = Model::new("example");
let x = model.add_var("x", 0.0, 10.0);
let y = model.add_var("y", 0.0, 10.0);
model.add_constraint(constraint!((x + y) <= 8.0));
model.minimize(2.0 * x + y);
let result = model.solve().unwrap();
assert!((result[x] + result[y]).abs() < 1e-4);
