Dict-Derive

Derive macro for PyO3's FromPyObject trait. The derived implementation turns a Python's dict into your Rust struct.

Usage

Add the library to your Cargo.toml together with PyO3: [dependencies] pyo3 = "0.7.0" dict_derive = "0.1.0"

Import the derive implementation and use it on your structs: ```rust extern crate dict_derive;

use dict_derive::FromPyObject;

[derive(FromPyObject)]

struct User { name: String, email: String, age: u32, } ```

Then you can use your structs as arguments in your PyO3 functions: ```rust extern crate pyo3; use pyo3::prelude::*; use pyo3::wrap_pyfunction;

[pyfunction]

fn getcontactinfo(user: User) -> PyResult { Ok(format!("{} - {}", user.name, user.email)) } ```

And then call your functions using normal python dicts: ```

import mylib mylib.getcontactinfo({"name": "Thor", "email": "thor@asgard.com", "age": 23}) 'Thor - thor@asgard.com' ```
