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.

## Calling Rust code from Python on Linux: A complete guide This guide will help you run the Python code `python3 -c 'import magic; print(magic.do_add(3, 4))'` and call the Rust function `do_add` to calculate the sum of 3 and 4. ### Prerequisites: * **Linux machine:** This guide is specifically for Linux. * **Rust compiler:** Install Rust by following the instructions on https://www.rust-lang.org/tools/install * **Python 3:** Make sure you have Python 3 installed. Check with `python3 --version`. * **CMake:** Install CMake by following the instructions on https://cmake.org/install/ ### Steps: 1. **Create a new Rust project:**

   cargo new magic
   cd magic
   

2. **Define the `do_add` function in `src/lib.rs`:**

   #[no_mangle]
   pub extern "C" fn do_add(a: i32, b: i32) -> i32 {
       a + b
   }
   

- `#[no_mangle]` prevents Rust from mangling the function name, making it accessible from Python. - `pub extern "C"` defines the function as a C function, allowing Python to call it. 3. **Build the Rust library:**

   cargo build --release
   

This will generate a library file (`magic.so` or `magic.dylib` depending on your platform) in the `target/release` directory. 4. **Create a Python wrapper:** Create a new file named `magic.py` in your project directory and add the following code:

   from ctypes import CDLL

   lib = CDLL("./target/release/magic.so")  # Adjust path if needed
   do_add = lib.do_add
   do_add.restype = int  # Specify return type

   result = do_add(3, 4)
   print(result)
   

This code: - Loads the Rust library using `ctypes`. - Defines a function `do_add` that corresponds to the Rust function. - Sets the return type of `do_add` to be `int`. - Calls `do_add` with 3 and 4 as arguments and prints the result. 5. **Run the Python code:**

   python3 magic.py
   

This should print the sum, which is 7. ### Conclusion Now you have successfully called the Rust function `do_add` from Python and calculated the sum of 3 and 4. Remember to adjust the library path in `magic.py` if you placed the library file in a different location.

## Setting Up the Project 1. **Install Rust:** - Follow the instructions on the official Rust website (https://www.rust-lang.org/tools/install) to install Rust on your Linux machine. - Verify the installation by running `rustc --version` in your terminal. 2. **Create a Cargo Project:** - Open a terminal and navigate to the directory where you want to create your project. - Run `cargo new rust_adder` to create a new Cargo project named `rust_adder`. - This command will create a directory with the same name and populate it with the basic structure of a Rust project. ## Implementing the Rust Function 1. **Open `src/main.rs`:** - Navigate to the `src` directory within the `rust_adder` project. - Open the `main.rs` file in your preferred text editor. 2. **Define the `do_add` Function:** - Replace the existing code in `main.rs` with the following:

fn do_add(a: i32, b: i32) -> i32 {
    a + b
}

#[cfg(test)]
mod tests {
    use super::*;

    #[test]
    fn test_do_add() {
        assert_eq!(do_add(3, 4), 7);
    }
}

This code defines a function called `do_add` that takes two integer arguments (`a` and `b`) and returns their sum as an integer. It also includes a test case to ensure the function works as expected. 3. **Compile the Rust Code:** - In the terminal, navigate back to the root of the `rust_adder` project. - Run `cargo build` to compile the Rust code. This will create a binary file named `target/debug/rust_adder` (or `target/release/rust_adder` if you used the `--release` flag). ## Building the Python Interface 1. **Install cffi:** - Run `pip install cffi` in your terminal to install the C Foreign Function Interface (cffi) library. This library allows Python to call functions written in other languages, including Rust. 2. **Create a Python Wrapper:** - Create a new Python file (e.g., `adder.py`) in the same directory as your Rust project. - Add the following code to `adder.py`:

from cffi import FFI

ffi = FFI()
ffi.dlopen("./target/debug/librust_adder.so")  # Adjust path if needed

c_do_add = ffi.CData("int (*)(int, int)")
c_do_add.set_ptr(ffi.addressof(ffi.C.do_add, 'int (*)(int, int)'))

def do_add(a, b):
    return c_do_add(a, b)

This code uses cffi to load the compiled Rust library (`librust_adder.so`) and access the `do_add` function. It then defines a Python function `do_add` that wraps the Rust function, allowing you to call it from Python. ## Running the Code 1. **Execute the Python Script:** - In your terminal, navigate to the directory containing `adder.py`. - Run `python3 adder.py` to execute the script. - You should see the output `7` printed to the console, indicating that the Rust function was successfully called and the sum was calculated correctly. ## Additional Notes - You can adjust the path to the Rust library in `adder.py` if you compiled it to a different location or with a different name. - If you encounter any errors during the process, make sure you have installed all the required dependencies and that the paths and function names are correct. - For more advanced use cases, you can explore additional features of cffi, such as passing complex data structures between Python and Rust.

## Setting Up the Project 1. **Install Rust:** - Follow the instructions on the official Rust website (https://www.rust-lang.org/tools/install) to install Rust on your Linux machine. 2. **Create a Cargo Project:** - Open a terminal and create a new directory for your project. - Inside the directory, run the following command to initialize a new Cargo project:

        cargo new magic
        

- This will create a new directory called `magic` with the basic structure for your Rust project. 3. **Add Python Bindings:** - In your project's `Cargo.toml` file, add the following dependencies under the `[dependencies]` section:

        pyo3 = { version = "0.15", features = ["extension-module"] }
        

- This will add the necessary libraries for creating Python bindings for your Rust code. ## Implementing the Rust Function 1. **Create the `src/lib.rs` file:** - In the `magic` directory, create a file named `src/lib.rs`. This file will contain your Rust code. 2. **Implement the `do_add` function:** - In the `src/lib.rs` file, add the following code:

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

- This defines a function called `do_add` that takes two integer arguments and returns their sum. The `#[pyfunction]` annotation tells pyo3 to expose this function to Python. ## Building the Rust Library 1. **Build the library:** - In the terminal, navigate to the project directory and run the following command to build the Rust library:

        cargo build --release
        

- This will create a shared library file in the `target/release` directory. ## Creating the Python Wrapper 1. **Create the `magic.py` file:** - In the `magic` directory, create a file named `magic.py`. This file will act as a Python wrapper for your Rust library. 2. **Import the library:** - In the `magic.py` file, add the following code:

        import pyo3

        # Assuming your shared library is named "magic.so"
        pyo3.init_module(module_name="magic", lib_name="magic.so")

        from . import magic

- This code initializes the pyo3 module and imports the Rust library as a Python module named `magic`. ## Testing the Integration 1. **Run the Python script:** - In the terminal, navigate to the `magic` directory and run the following command:

        python3 -c 'import magic; print(magic.do_add(3, 4))'
        

- If everything is set up correctly, this should print the output `7`. ## Summary With these steps, you have successfully integrated your Rust function into a Python script. You can now use the `do_add` function from your Rust library within your Python code.
