ChatGPT 写的 Rust 调用 Python C-API 的例子
use std::os::raw::{c_char, c_int};use std::ffi::CString;use libc::{c_double, c_void};#[link(name = "python3.8")]extern "C" {fn Py_Initialize();fn Py_Finalize();fn Py_BuildValue(format: *const c_char, ...) -> *mut c_void;}fn main() {unsafe {// 初始化 Python 解释器Py_Initialize();// 构建一个 Python 元组对象,并打印它let x = 1.23 as c_double;let y = 4.56 as c_double;let format = CString::new("dd").unwrap().as_ptr();let result = Py_BuildValue(format, x, y);let s = CString::from_raw(result as *mut c_char).into_string().unwrap();println!("{}", s);// 关闭 Python 解释器Py_Finalize();}}pyo3-ffi: Python-API bindings for the PyO3 ecosystem
