Daniel Grunwald b37fa220df On Python 2.7, PyString now corresponds to `basestring` instead of `str`. `<str as ToPyObject>::ObjectType` now always is `PyString` (previously the type differed between Python 2.7 and 3.x) `PyStringData` allows zero-copy access to Python's underlying string representation.		2016-05-05 07:26:52 +02:00

rust-cpython

Rust bindings for the python interpreter.

Documentation
Cargo package: cpython

Supported Python versions:

Python 2.7
Python 3.3
Python 3.4
Python 3.5

Supported Rust version:

Rust 1.7.0 or later

Usage

To use cpython, add this to your Cargo.toml:

[dependencies]
cpython = { git = "https://github.com/dgrunwald/rust-cpython.git" }

Example program displaying the value of sys.version:

extern crate cpython;

use cpython::Python;
use cpython::ObjectProtocol; //for call method

fn main() {
    let gil = Python::acquire_gil();
    let py = gil.python();

    let sys = py.import("sys").unwrap();
    let version: String = sys.get(py, "version").unwrap().extract(py).unwrap();

    let os = py.import("os").unwrap();
    let getenv = os.get(py, "getenv").unwrap();
    let user: String = getenv.call(py, ("USER",), None).unwrap().extract(py).unwrap();

    println!("Hello {}, I'm Python {}", user, version);
}
