pounce-linsol 0.12.0

Symmetric linear-solver trait layer for POUNCE (port of Ipopt's Algorithm/LinearSolvers/Ip{SymLinearSolver,SparseSymLinearSolverInterface,TSymLinearSolver,TSymScalingMethod,TripletToCSRConverter}). No FFI; concrete backends are pounce-feral (the pure-Rust sparse LDLᵀ default) and the optional pounce-hsl (MA57).

//! POUNCE symmetric linear-solver trait layer.
//!
//! Port of Ipopt's `src/Algorithm/LinearSolvers/`:
//!
//! * [`sym_solver`] — high-level [`SymLinearSolver`] trait
//!   (port of `IpSymLinearSolver.hpp`).
//! * [`sparse_sym_iface`] — low-level [`SparseSymLinearSolverInterface`]
//!   trait that backends like MA57 / MUMPS / FERAL implement
//!   (port of `IpSparseSymLinearSolverInterface.hpp`).
//! * [`status`] — [`ESymSolverStatus`] return enum
//!   (port of the enum in `IpSymLinearSolver.hpp`).
//!
//! Concrete backends live outside this crate: `pounce-hsl` ships the
//! MA57 backend in v1.0; MUMPS and FERAL are slotted behind the same
//! traits in v1.1.
