Rust Extension Example

This is an example of a Rust extension for Python, using PyO3 and rust-numpy. See the blog post for a more detailed walkthrough.

Files

create-msgpack.py - script to create the input msgpack file
process-empty.py - script that demonstrates the (de-)serialization cost of big NumPy arrays through process workers
rust-ext-example.py - script that demonstrates the main example
src/ - Rust source code

Setup

Create a venv and install from requirements.txt. Then run create-msgpack.py to create the input msgpack file.

For the Rust extension, run (cd take_iter && maturin develop --release). This will build the extension and install it in the venv.

Run python rust-ext-example.py to run the example.
