- pydantic-core: Core validation logic for pydantic written in Rust.
- cryptography: Python cryptography library with some functionality in Rust.
- orjson: Fast, correct Python JSON library supporting dataclasses, datetimes, and numpy

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();
    }
}
