Setuptools plugin for Rust extensions

setuptools-rust is a plugin for setuptools to build Rust Python extensions implemented with PyO3 or rust-cpython.

Compile and distribute Python extensions written in Rust as easily as if they were written in C.

Setup

For a complete example, see html-py-ever.

First, you need to create a bunch of files:

setup.py

from setuptools import setup
from setuptools_rust import Binding, RustExtension

setup(
    name="hello-rust",
    version="1.0",
    rust_extensions=[RustExtension("hello_rust.hello_rust", binding=Binding.PyO3)],
    packages=["hello_rust"],
    # rust extensions are not zip safe, just like C-extensions.
    zip_safe=False,
)

For a complete reference of the options supported by the RustExtension class, see the API reference.

pyproject.toml

[build-system]
requires = ["setuptools", "wheel", "setuptools-rust"]

MANIFEST.in

This file is required for building source distributions

include Cargo.toml
recursive-include src *

Usage

You can use same commands as for c-extensions. For example:

>>> python ./setup.py develop
running develop
running egg_info
writing hello-rust.egg-info/PKG-INFO
writing top-level names to hello_rust.egg-info/top_level.txt
writing dependency_links to hello_rust.egg-info/dependency_links.txt
reading manifest file 'hello_rust.egg-info/SOURCES.txt'
writing manifest file 'hello_rust.egg-info/SOURCES.txt'
running build_ext
running build_rust
cargo build --manifest-path extensions/Cargo.toml --features python3
    Finished debug [unoptimized + debuginfo] target(s) in 0.0 secs

Creating /.../lib/python3.6/site-packages/hello_rust.egg-link (link to .)

Installed hello_rust
Processing dependencies for hello_rust==1.0
Finished processing dependencies for hello_rust==1.0

Or you can use commands like bdist_wheel (after installing wheel). See also the notes in the documentation about building wheels.

Cross-compiling is also supported, using one of crossenv, cross or cargo-zigbuild. For examples see the test-cross-compile and test-cross and test-zigbuild Github actions jobs in ci.yml.

By default, develop will create a debug build, while install will create a release build.

Commands

build - Standard build command will also build all rust extensions.
build_rust - Command builds all rust extensions.
clean - Standard clean command executes cargo clean for all rust extensions.
