Maturin

As explained in Refactoring to Rust

Maturin is a build and packaging tool for developing Python modules implemented in Rust.

Maturin is a command-line tool for developing Python modules implemented in Rust. It sets up development environments for Rust-based Python extensions and builds distribution-ready packages. section 6.4 section 6.7

A typical development workflow is:

  • Create and activate a Python virtual environment, because maturin develop must run inside one. section 6.4
  • Run maturin develop to compile the Rust extension and install it for immediate Python use. section 6.7

Importing a Rust extension

Before building, importing rust_json fails with ModuleNotFoundError. After activating the environment and running maturin develop, Python imports rust_json successfully and can call rust_json.sum on a JSON string.

How Refactoring to Rust covers it

How deep it goes
Explains installation, virtual-environment setup, compilation, installation, and import validation, but not maturin internals.
Examples
Uses the rust_json extension, maturin develop, Python imports, and a JSON-line processing program.
What it assumes
Assumes basic Python package installation and virtual-environment commands while introducing Rust extension integration through PyO3.
What you can do after
Operate maturin develop to compile, install, import, and call a Rust-based Python module inside an isolated environment.
How it connects
Connects Rust, Python, PyO3, Python virtual environments, and Cargo-based extension configuration.
