PyO3


PyO3 有哪些应用？


polars: Fast multi-threaded DataFrame library in Rust | Python | Node.js.
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


PyO3 前身：rust-cpython


Maturin: Build and publish crates with pyo3, rust-cpython and cffi bindings as well as rust binaries as python packages

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();

}

}
