How to get the size of typed memoryviews in cython

Question

Is it possible to get the size of a MemoryView in cython? Ideally, I'm looking for something like arr.shape in numpy.

From http://docs.python.org/3.3/library/stdtypes.html#memoryview

len(view) is equal to the length of tolist. If view.ndim = 0, the length is 1. If view.ndim = 1, the length is equal to the number of elements in the view. For higher dimensions, the length is equal to the length of the nested list representation of the view. The itemsize attribute will give you the number of bytes in a single element.
