cymove

This package is DEPRECATED since std::move support is merged to Cython and available as of v0.29.17 (2020-04-26).

cymove is a header (pxd) only wrapper around C++11 std::move function. It allows using move semantics from cython code.

Installation

pip install cymove

Example Usage

example.pyx:

# distutils: language = c++

from libcpp.memory cimport make_shared, shared_ptr, nullptr
from cymove cimport cymove as move

cdef shared_ptr[int] ptr1, ptr2
cdef int* raw_ptr

ptr1 = make_shared[int](5)
raw_ptr = ptr1.get()
ptr2 = move(ptr1)

assert ptr2.get() == raw_ptr
assert ptr1 == nullptr

print("OK!")

Compile & run:

$ cythonize -3 -i example.pyx
$ python3 -c "import example"
OK!
