ufuncs are implemented in C. We provide so-called loop functions that iterate over contiguous segments of the operand arrays. We use a custom code generator to make implementations for all of the types. Here are the ones that correspond to `np.invert`. (the bool implementation uses the `logical_not` loop). https://github.com/numpy/numpy/blob/main/numpy/core/src/umath/loops.c.src#L612-L626 -- Robert Kern
