Trait good_lp::IntoAffineExpression

pub trait IntoAffineExpression {
    type Iter: IntoIterator<Item = (Variable, f64)>;
    fn linear_coefficients(self) -> Self::Iter;

    fn constant(&self) -> f64 { ... }
}

An element that can be expressed as a linear combination of variables plus a constant

Required methods

fn linear_coefficients(self) -> Self::Iter

An iterator over variables and their coefficients. For instance a + 2b - 3a - 7 should yield [(a, -2), (b, 2)]

Provided methods

fn constant(&self) -> f64

The constant factor in the expression. For instance, a + 2b - 7 will give -7
