[Cython] __next__ | not being able to use cpdef

[Jelle Feringa]

Hi,

I just started to use Cython, for writing a set of fast iterators.
Go easy on me, this is all new territory ;')

Now, the thing is that if I understood correctly, it would be faster  
to have the __next__ method types a cpdef int __next__(self )
When I do so the module fails to compile.
Is there a specific reason why this is so?
Still, using the object below, accessing objects from an iterable is  
twice as fast.

Thanks,

cdef class FastLoopObj1d:

     cdef int N, i
     cdef object obj

     def __init__(self, n, obj ):
         self.N = n-1
         self.i = 0
         self.obj = obj

     def __iter__(self):
         return self

     # no cpdef allowed?
     def __next__( self ):
         if self.i < self.N:
             self.i+=1
             return self.obj[self.i]
         else:
             raise StopIteration
