Initial Query

I want to call some rust code from python on a linux machine. Specifically, I want to be able to run python3 -c 'import magic; print(magic.do_add(3, 4))' and have it give me the sum of these numbers. Here, do_add should be a rust function that adds two integers. Please give me a complete set of instructions for how to make this run, so that when I run this code as-is it will work.

Output

To call Rust code from Python, you can use the `PyO3` crate, which allows you to create Python extensions in Rust. Below is a step-by-step guide to achieve your goal: ### Step 1: Install Rust and Cargo If you haven't already installed Rust, you can do so by running: 

1
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
Follow the on-screen instructions to install Rust and Cargo (Rust's package manager). ### Step 2: Create a New Rust Library Create a new Rust library project: 
1
2
cargo new --lib rust_magic
cd rust_magic
### Step 3: Add Dependencies Edit the `Cargo.toml` file to add the `PyO3` dependency: 
 1

[package]
name = "rust_magic"
version = "0.1.0"
edition = "2021"

[lib]
name = "magic"
crate-type = ["cdylib"]

[dependencies]
pyo3 = { version = "0.15", features = ["extension-module"] }
### Step 4: Write the Rust Code Edit the `src/lib.rs` file to define the `do_add` function:

use pyo3::prelude::*;

#[pyfunction]
fn do_add(a: i32, b: i32) -> i32 {
    a + b
}

#[pymodule]
fn magic(_py: Python, m: &PyModule) -> PyResult<()> {
    m.add_function(wrap_pyfunction!(do_add, m)?)?;
    Ok(())
}
### Step 5: Build the Rust Library Build the Rust library as a shared object file: 
1
cargo build --release
This will generate a shared object file (`.so`) in the `target/release/` directory. ### Step 6: Copy the Shared Object to Python's Path Copy the generated `.so` file to a directory where Python can find it. For example: 
1
cp target/release/librust_magic.so /usr/local/lib/python3.8/site-packages/magic.so
Make sure to adjust the Python version in the path to match your environment. ### Step 7: Test the Python Code Now you can test the Python code: 
1
python3 -c 'import magic; print(magic.do_add(3, 4))'
This should output `7`. ### Step 8: (Optional) Install the Module for Easy Access If you want to make the module easily accessible, you can create a `setup.py` file and install it using `pip`. Create a `setup.py` file: 
 1

from setuptools import setup
from setuptools_rust import Binding, RustExtension

setup(
    name="magic",
    version="0.1",
    rust_extensions=[RustExtension("magic.magic", binding=Binding.PyO3)],
    packages=["magic"],
    zip_safe=False,
)
Install the module: 
1
pip install .
Now you can use the `magic` module from anywhere in your Python environment. ### Summary 1. Install Rust and Cargo. 2. Create a new Rust library project. 3. Add `PyO3` as a dependency in `Cargo.toml`. 4. Write the Rust code in `src/lib.rs`. 5. Build the Rust library with `cargo build --release`. 6. Copy the `.so` file to a directory where Python can find it. 7. Test the Python code. This setup allows you to call Rust functions from Python seamlessly.

Query

Now please conver this answer into a JSON array that packages it all up so I don't need to think and can just copy files to specific locations and then run things. Format your answer {"path/to/file": "contents of rust file", "path/to/python_file": "contents of any necessary python file that exposes do_add", "build.sh": "contents of a bash file to build the project", ... # any other files necessary } The only thing I will do is put files in the right place and run `bash build.sh`. Do not give any explanation of the code. ONLY ANSWER WITH A SINGLE JSON OBJECT. Your answer should start
