Crate pythonize

Expand description

This crate converts Rust types which implement the Serde serialization traits into Python objects using the PyO3 library.

Pythonize has two public APIs: pythonize and depythonize.

Examples

use serde::{Serialize, Deserialize};
use pyo3::Python;
use pythonize::{depythonize, pythonize};

#[derive(Debug, Serialize, Deserialize, PartialEq)]
struct Sample {
    foo: String,
    bar: Option<usize>
}

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

let sample = Sample {
    foo: "Foo".to_string(),
    bar: None
};

// Rust -> Python
let obj = pythonize(py, &sample).unwrap();

assert_eq!("{'foo': 'Foo', 'bar': None}", &format!("{}", obj.as_ref(py).repr().unwrap()));

// Python -> Rust
let new_sample: Sample = depythonize(obj.as_ref(py)).unwrap();

assert_eq!(new_sample, sample);
