Some functions in SciPy take as arguments callback functions, which can either be python callables or low-level compiled functions. Using compiled callback functions can improve performance somewhat by avoiding wrapping data in Python objects. Such low-level functions in SciPy are wrapped in `LowLevelCallable` objects, which can be constructed from function pointers obtained from ctypes, cffi, Cython, or contained in Python `PyCapsule` objects. .. seealso:: Functions accepting low-level callables: `scipy.integrate.quad`, `scipy.ndimage.generic_filter`, `scipy.ndimage.generic_filter1d`, `scipy.ndimage.geometric_transform` Usage examples: :ref:`ndimage-ccallbacks`, :ref:`quad-callbacks` Parameters ---------- function : {PyCapsule, ctypes function pointer, cffi function pointer} Low-level callback function. user_data : {PyCapsule, ctypes void pointer, cffi void pointer} User data to pass on to the callback function. signature : str, optional Signature of the function. If omitted, determined from *function*, if possible. Attributes ---------- function Callback function given. user_data User data given. signature Signature of the function. Methods ------- from_cython Class method for constructing callables from Cython C-exported functions. Notes ----- The argument ``function`` can be one of: - PyCapsule, whose name contains the C function signature - ctypes function pointer - cffi function pointer The signature of the low-level callback must match one of those expected by the routine it is passed to. If constructing low-level functions from a PyCapsule, the name of the capsule must be the corresponding signature, in the format:: return_type (arg1_type, arg2_type, ...) For example:: "void (double)" "double (double, int *, void *)" The context of a PyCapsule passed in as ``function`` is used as ``user_data``, if an explicit value for ``user_data`` was not given. rNcTURXU5n[RXX45$N)_parse_callbacktuple__new__)clsfunction user_data signatureitems rrLowLevelCallable.__new__hs*""8 B}}S"=>>rc@SUR<SUR<S3$)NzLowLevelCallable(, ))rr selfs r__repr__LowLevelCallable.__repr__ns!"4=="32dnn5GqIIrc.[RUS5$)Nrr __getitem__r's rrLowLevelCallable.functionq  q))rc.[RUS5$)Nr,r's rr LowLevelCallable.user_dataur/rcV[R"[RUS55$)Nr)rget_capsule_signaturerr-r's rr!LowLevelCallable.signatureys 11%2C2CD!2LMMrc[5er) ValueError)r(idxs rr-LowLevelCallable.__getitem__}s lrcURUnU"XSU5$![anSn[U5UeSnAf[anSU<S3n[U5UeSnAff=f)a Create a low-level callback function from an exported Cython function.
