Crate pounce_linsol 

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.
