Output

To call Rust code from Python on a Linux machine, you can use the **PyO3** library along with **maturin** to create a Python extension module in Rust. Below are step-by-step instructions to achieve this, enabling you to run: 

1
python3 -c 'import magic; print(magic.do_add(3, 4))'
and get the sum of the two numbers (`7`) as output. ## Prerequisites 1. **Rust Toolchain**: Ensure you have Rust installed. 2. **Python 3**: Ensure you have Python 3 installed. 3. **Maturin**: A tool for building and publishing Rust-based Python packages. 4. **Cargo**: Rust’s package manager, installed with Rust. ## Step-by-Step Guide ### 1. Install Rust If you haven't installed Rust yet, install it using `rustup`: 
1
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
Follow the on-screen instructions to complete the installation. After installation, ensure that the Rust toolchain is up to date: 
1
rustup update
### 2. Install Maturin Maturin is a tool that simplifies building and publishing Rust-based Python packages. Install it using `pip`: 
1
pip install maturin
Ensure that `pip` corresponds to the Python version you intend to use (Python 3). ### 3. Create a New Rust Project Create a new directory for your project and navigate into it: 
1
2
mkdir magic
cd magic
Initialize a new Rust project using Cargo: 
1
cargo init --lib
This creates a new Rust library project. ### 4. Configure `Cargo.toml` Open the `Cargo.toml` file in your preferred text editor and modify it to include the necessary dependencies and configurations for PyO3 and Maturin. Here’s how your `Cargo.toml` should look: 
 1

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

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

[dependencies]
pyo3 = { version = "0.20", features = ["extension-module"] }

[build-dependencies]
maturin = "0.16"
**Explanation of the Configuration:** - **`crate-type = ["cdylib"]`**: Specifies that the crate produces a C-compatible dynamic library, which is necessary for Python to load it. - **`pyo3`**: The Rust crate for Python bindings. The `extension-module` feature enables building Python extension modules. - **`maturin`**: Included as a build dependency to assist with building the Python module. ### 5. Implement the `do_add` Function in Rust Open `src/lib.rs` and replace its contents with the following Rust code: 
 1

use pyo3::prelude::*;

/// Adds two integers and returns the result.
///
/// # Arguments
///
/// * `a` - An integer.
/// * `b` - Another integer.
///
/// # Example
///
///
python /// import magic /// result = magic.do_add(3, 4) /// print(result) # Outputs: 7 ///

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

/// A Python module implemented in Rust.
#[pymodule]
fn magic(_py: Python, m: &PyModule) -> PyResult<()> {
    m.add_function(wrap_pyfunction!(do_add, m)?)?;
    Ok(())
}
**Explanation of the Code:** - **`#[pyfunction]`**: Macro to expose the Rust function `do_add` to Python. - **`#[pymodule]`**: Macro to define the Python module `magic` and register the `do_add` function within it. ### 6. Build and Install the Python Module Use `maturin` to build and install the module into your current Python environment. Run the following command in the root directory of your project (where `Cargo.toml` is located): 
1
maturin develop
**What This Does:** - **Builds** the Rust code as a Python extension module. - **Installs** the module into your current Python environment, making it available for import. **Note:** If you encounter any issues with environment variables or permissions, ensure that your Rust and Python environments are correctly set up and that you have the necessary permissions to install Python packages. ### 7. Test the Python Module After successful installation, you can test the module using the Python command provided. Run the following command in your terminal: 
1
python3 -c 'import magic; print(magic.do_add(3, 4))'
**Expected Output:** 
1
7
### 8. (Optional) Verify Installation To further verify that the module is correctly installed and accessible, you can use an interactive Python session: 
1
python3
Then, within the Python prompt: 
1
2
3
import magic
result = magic.do_add(10, 20)
print(f"The sum is: {result}")
**Expected Output:** 
1
The sum is: 30
## Troubleshooting Tips - **Rust Installation Issues**: Ensure that Rust is correctly installed and that `cargo` is available in your `PATH`. - **Maturin Installation Issues**: Ensure that `maturin` is installed in the Python environment you intend to use. You can verify by running `maturin --version`. - **Python Environment**: It's recommended to use a virtual environment to manage Python packages and dependencies. You can create one using `venv`: 
1
2
3
4
  python3 -m venv venv
  source venv/bin/activate
  pip install maturin
- **Compiler Errors**: Ensure that you have the necessary build tools installed on your Linux machine. You may need to install `build-essential`: 
1
2
3
  sudo apt update
  sudo apt install build-essential
- **Linker Issues**: If you encounter linker errors, ensure that you have the necessary system libraries and that your Rust toolchain is up to date. ## Final Notes Using **PyO3** with **maturin** provides a seamless way to build and integrate Rust code as Python modules. This approach leverages Rust’s performance and safety features while retaining Python’s ease of use, making it ideal for performance-critical applications or when you want to leverage existing Rust libraries in Python. Feel free to expand upon this foundation by adding more functions, handling different data types, or integrating more complex Rust logic into your Python modules.
