I'm trying to use a struct defintion declared in another package:
import PriceDBCython as PriceDBCython
cimport PriceDBCython as PriceDBCython
def transform():
cdef i, numRows
cdef PriceDBCython.PriceRow * dataRowsCython
Here is the traceback:
def transform():
cdef i, numRows
cdef PriceDBCython.PriceRow * dataRowsCython
^

def transform():
