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.

Here's a step-by-step guide to create a Python module in Rust using PyO3: 1. **Install Prerequisites**

# Install Rust
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
source $HOME/.cargo/env

# Install Python development headers
sudo apt-get install python3-dev
2. **Create Rust Project** 
1
2
cargo new --lib magic
cd magic
3. **Edit Cargo.toml**

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

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

[dependencies]
pyo3 = { version = "0.20.0", features = ["extension-module"] }
4. **Edit src/lib.rs**

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(())
}
5. **Build the Module** 
1
cargo build --release
6. **Rename and Prepare the Shared Library** 
1

3
4
5
# Create a symlink or copy the library
ln -s target/release/libmagic.so magic.so

# Alternative: copy the file
# cp target/release/libmagic.so magic.so
7. **Run the Python Command** 
1
PYTHONPATH=. python3 -c 'import magic; print(magic.do_add(3, 4))'
This will output: 
1
7
**Note:** The `PYTHONPATH=.` tells Python to look in the current directory for the module. You can also: - Move `magic.so` to a directory in your Python path - Install it system-wide (requires root) - Use a virtual environment and install it there The shared library must be named exactly `magic.so` for Python to recognize it as the `magic` module.

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
