The primary goal of
rb-sys is to make building native Ruby extensions in Rust easier than it would be in C. If
it's not easy, it's a bug.
- Battle-tested Rust bindings for the Ruby C API
- Support for Ruby 2.4+
- Supports all major platforms (Linux, macOS, Windows)
- Cross compilation of gems
- Integration with
- Ruby on Rust Book 📖 to describe how to build, test, and deploy a Rusty Ruby Gem
- Contributing Docs 💻 to get started in making your first contributions to rb-sys
rb-sysgem 💎 to learn more about the
rb-sysgem for compiling extensions
- Battle-tested Ruby FFI bindings for Rust (via
- GitHub action to setup a test environment in CI
- GitHub action to easily cross compile in CI
- Test helpers) for testing Ruby extensions in Rust
Below are some examples of how to use
rb-sys to build native Rust extensions. Use these as a starting point for your
building your own gem.
magnusto package the rust
wasmtimelibrary as a Ruby gem.
oxi-testgem is the canonical example of how to use
rb-sys. It is a minimal, fully tested with GitHub actions, and cross-compiles native gem binaries. This should be your first stop for learning how to use
- Docs for the
rb_sysgem and using it with an
magnusrepo has some solid examples.
- This demo repository that @ianks made for a talk has a gem which has 4 native extensions in the
- This PR for the
yrbgem shows how to integrate
magnusinto an existing gem.
- A guide for setting debug breakpoints in VSCode is available.
- Ruby: 2.4+ (for full compatibility with Rubygems)
- Rust: 1.60+
We support cross compilation to the following platforms (this information is also available in the
directory for automation purposes):
