pounce-nlp 0.3.0

//! POUNCE NLP-side glue.
//!
//! Port of Ipopt's `src/Interfaces/`. This crate provides:
//!
//! * The user-facing [`tnlp::TNLP`] trait for problem definition
//!   (port of `IpTNLP.{hpp,cpp}`).
//! * Public return-code enums [`return_codes::ApplicationReturnStatus`]
//!   and [`return_codes::AlgorithmMode`] (port of `IpReturnCodes_inc.h`)
//!   plus algorithm-side [`alg_types::SolverReturn`] (port of
//!   `IpAlgTypes.hpp`).
//! * Per-solve [`solve_statistics::SolveStatistics`] counters (port of
//!   `IpSolveStatistics.{hpp,cpp}`).
//! * `TNLPAdapter` and `OrigIpoptNlp`, the bound/constraint splitter
//!   chain feeding the algorithm-side IPM.
//!
//! The user-facing `IpoptApplication` lives in `pounce-algorithm`
//! (since `optimize_tnlp` orchestrates the algorithm). It is
//! re-exported as `pounce_algorithm::IpoptApplication`. The dependency
//! direction is `pounce-algorithm → pounce-nlp`; this crate must not
//! import `pounce-algorithm` types.
