不是所有的c++方法都包装在Cython的cpplib中,而是使用
already wrapped methods
作为蓝图,很容易包装缺少的功能-无需重新实现算法(无论多么简单)
例如:
%%cython --cplus
from libcpp.vector cimport vector
# wrap it yourself!
cdef extern from "<algorithm>" namespace "std" nogil:
OutputIter merge[InputIter1, InputIter2, OutputIter] (InputIter1 first1, InputIter1 last1,
InputIter2 first2, InputIter2 last2,
OutputIter result)
# for ilustration purposes:
cdef vector[int] v1=[1,3,5]
cdef vector[int] v2=[2,4,6]
cdef vector[int] out = vector[int](6)
merge(v1.begin(), v1.end(), v2.begin(), v2.end(), out.begin())
print(out)
[1,2,3,4,5,6]
