Fields

x: Vec<Number>

lambda_g: Vec<Number>

lambda_x: Vec<Number>

obj: Number

status: SqpStatus

n_iter: u32

n_qp_solves: u32

n_qp_working_set_changes: u32

Active-set changes (adds + drops) summed over every step QP solved during this call — the inner work a working-set warm start exists to avoid. Reported separately from n_iter because the two move independently: on a QP-shaped NLP the outer loop always terminates in one iteration, so the entire warm-start effect shows up here and nowhere else.

Excludes second-order-correction QPs, whose stats the line search does not surface.

final_stationarity: Number

Final stationarity residual (max-norm of ∇f + Jᵀ λ_g + λ_x).

final_constr_viol: Number

Final constraint violation (max-norm of c(x*) for equalities plus bound-violation slack).

working_set: Option<WorkingSet>

Final QP working set, suitable for warm-starting the next optimize_with_warm_start call (§6 design-note contract). None only when no QP was solved (e.g. cold-start declared the iterate optimal at the very first KKT check).
