Enum Outcome 

pub enum Outcome {
    Accepted,
    TinyStep,
    Failed,
}

Outcome of the backtracking line search. Mirrors the booleans upstream returns through accept_ plus the tiny_step_flag on IpoptData.

Variants

Accepted

Trial point accepted at the recorded alpha.

TinyStep

alpha fell below alpha_min_frac × current α₀ ⇒ tiny step. Caller maps to STEP_BECOMES_TINY in upstream’s exception flow.

Failed

All α reductions rejected; the caller hands off to restoration.
