Module ode_c 

C FFI functions for creating, configuring, solving, and destroying OdeWrapper objects.

Provides extern "C" functions for the full lifecycle of an ODE solver:

• diffsol_ode_wrapper_new_* — constructors (feature-gated by JIT backend or external).
• diffsol_ode_wrapper_get_* / diffsol_ode_wrapper_set_* — getters/setters for tolerances, time settings, solver type, and linear solver.
• diffsol_ode_wrapper_y0, diffsol_ode_wrapper_rhs, diffsol_ode_wrapper_rhs_jac_mul — low-level RHS evaluation.
• diffsol_ode_wrapper_solve, diffsol_ode_wrapper_solve_dense, diffsol_ode_wrapper_solve_fwd_sens, diffsol_ode_wrapper_solve_continuous_adjoint, diffsol_ode_wrapper_solve_adjoint_fwd, diffsol_ode_wrapper_solve_adjoint_bkwd — solve functions returning SolutionWrapper pointers.
• diffsol_ode_wrapper_free — free an OdeWrapper.
• Serialization: diffsol_ode_wrapper_serialize, diffsol_ode_wrapper_deserialize.
