This project is still pretty much a "tech demo" in this stage. What you can see above is all that works. And it took a lot of short cuts to even get that far. (And please don't run cargo test.)
Creating a wayland compositor library from the ground up is a daunting task, and I don't think I can do this just by myself. That's why this project is announced in this state - because I wanted to attract interests, and potentially collaborators to this project.
I tried to document the code base in its current state as best as I can. Have a look at the documentation, or the code base, and get in touch if you are interested:
- runa-core: base traits and types for a wayland compositor.
- runa-orbiter: wayland protocol impls based on
runa-core.
I am currently hanging out in the #runa channel on libra.chat.
- Have unittests for easily testable components.
- All of the core and stable wayland interfaces implemented. No more "not implemented" error.
- Fix interface versioning
- Crescent able to run as DRM master
- We likely want to create a crate for making accessing raw display devices and input devices easier. or use an existing crate. winit might become a viable option (rust-windowing/winit#2272)
- Support hardware accelerated clients
- Crescent can function as a minimal wayland compositor
- A tutorial for writing compositors with runa
- Xwayland support

Why runa, instead of other wayland libraries like wlroots, or smithay?
wlroots has a model that is not very suitable for a Rust binding - people has tried and failed at creating a binding for it. And even if I do manage to create a wlroots binding, it's not going to be ergonomic Rust.
As for smithay, runa's design philosophy is pretty different. First of all, smithay was created quite a few years back, and Rust has evolved a lot in that time. runa tries to take advantage of new Rust features, most notably
async, as much as possible. (this does unfortunately mean a nightly Rust compiler is required for now, at least until TAIT is stabilized).Also, runa took a page from other amazing Rust crates like smol and futures, and has a very modular design, unlike smithay which is everything inside a single crate. This way 1) users can bring their own implementation if what we provide is not suitable; 2) some of our crates can be useful outside runa.
