Setuptools rust extension plugin
Project description
Setuptools helpers for rust Python extensions implemented with PyO3 python binding.
Compile and distribute Python extensions written in rust as easily as if they were written in C.
Example
setup.py
from setuptools import setup
from setuptools_rust import Binding, RustExtension
setup(name='hello-rust',
version='1.0',
rust_extensions=[RustExtension('hello_rust._helloworld',
'Cargo.toml', binding=Binding.PyO3)],
packages=['hello_rust'],
# rust extensions are not zip safe, just like C-extensions.
zip_safe=False
)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 or bdist_egg.
You can build manylinux1 binary wheels using Docker:
docker run --rm -v `pwd`:/io quay.io/pypa/manylinux1_x86_64 /io/build-wheels.shbuild-wheels.sh example can be found here: https://github.com/PyO3/setuptools-rust/blob/master/example/build-wheels.sh
RustExtension
You can define rust extension with RustExtension class:
RustExtension(name, path, args=None, features=None, rust_version=None, quiet=False, debug=False)
The class for creating rust extensions.
- param str name:
the full name of the extension, including any packages – ie. not a filename or pathname, but Python dotted name. It is possible to specify multiple binaries, if extension uses Binsing.Exec binding mode. In that case first argument has to be dictionary. Keys of the dictionary corresponds to compiled rust binaries and values are full name of the executable inside python package.
- param str path:
path to the Cargo.toml manifest file
- param [str] args:
a list of extra argumenents to be passed to cargo.
- param [str] features:
a list of features to also build
- param str rust_version:
sematic version of rust compiler version – for example >1.14,<1.16, default is None
- param bool quiet:
Does not echo cargo’s output. default is False
- param bool debug:
Controls whether –debug or –release is passed to cargo. If set to None then build type is auto-detect. Inplace build is debug build otherwise release. Default: None
- param int binding:
Controls which python binding is in use. Binding.PyO3 uses PyO3 Binding.RustCPython uses rust-cpython Binding.NoBinding uses no binding. Binding.Exec build executable.
- param int strip:
Strip symbols from final file. Does nothing for debug build. Strip.No - do not strip symbols (default) Strip.Debug - strip debug symbols Strip.All - strip all symbols
- param bool script:
Generate console script for executable if Binding.Exec is used.
- param bool native:
Build extension or executable with “-C target-cpu=native”
- param bool optional:
if it is true, a build failure in the extension will not abort the build process, but instead simply not install the failing extension.
Commands
build - Standard build command builds all rust extensions.
build_rust - Command builds all rust extensions.
clean - Standard clean command executes cargo clean for all rust extensions.
check - Standard check command executes cargo check for all rust extensions.
