Enum Rejection 

pub enum Rejection {
    NotPositive,
    Infeasible,
    Unresolved,
    NotLower,
}

Why a step was turned down.

Variants

NotPositive

The damped model’s curvature is not positive.

Infeasible

The residuals cannot be evaluated where it leads.

Unresolved

Cut so short that the linearized model cannot tell it from no step.

NotLower

Where it leads, neither the sum nor the violation is definitely lower than at every point taken before.
