使用pybind11将C结构与另一个结构的数组绑定为成员可以通过以下步骤实现:
#include <pybind11/pybind11.h>
struct CStruct {
int value;
};
struct AnotherStruct {
float value;
};
struct MyStruct {
CStruct c;
AnotherStruct* array;
int size;
};
namespace py = pybind11;
PYBIND11_MODULE(my_module, m) {
py::class_<CStruct>(m, "CStruct")
.def(py::init<>())
.def_readwrite("value", &CStruct::value);
py::class_<AnotherStruct>(m, "AnotherStruct")
.def(py::init<>())
.def_readwrite("value", &AnotherStruct::value);
py::class_<MyStruct>(m, "MyStruct")
.def(py::init<>())
.def_readwrite("c", &MyStruct::c)
.def_readwrite("array", &MyStruct::array)
.def_readwrite("size", &MyStruct::size);
}
g++ -O3 -Wall -shared -std=c++11 -fPIC `python3 -m pybind11 --includes` bindings.cpp -o my_module`python3-config --extension-suffix`
import my_module
c = my_module.CStruct()
c.value = 10
another = my_module.AnotherStruct()
another.value = 3.14
my_struct = my_module.MyStruct()
my_struct.c = c
my_struct.array = [another]
my_struct.size = 1
print(my_struct.c.value) # 输出:10
print(my_struct.array[0].value) # 输出:3.14
print(my_struct.size) # 输出:1
这样,就成功地使用pybind11将C结构与另一个结构的数组绑定为成员,并可以在Python中使用。请注意,以上示例中的代码仅供参考,实际应用中可能需要根据具体情况进行适当修改。
