Vulkano

See also vulkano.rs.

Vulkano is a Rust wrapper around the Vulkan graphics API. It follows the Rust philosophy, which is that as long as you don't use unsafe code you shouldn't be able to trigger any undefined behavior. In the case of Vulkan, this means that non-unsafe code should always conform to valid API usage.

What does vulkano do?

• Provides a low-levelish API around Vulkan. It doesn't hide what it does, but provides some comfort types.
• Plans to prevent all invalid API usages, even the most obscure ones. The purpose of vulkano is not to simply let you draw a teapot, but to cover all possible usages of Vulkan and detect all the possible problems in order to write robust programs. Invalid API usage is prevented thanks to both compile-time checks and runtime checks.
• Can handle synchronization on the GPU side for you (unless you choose do that yourself), as this aspect of Vulkan is both annoying to handle and error-prone. Dependencies between submissions are automatically detected, and semaphores are managed automatically. The behavior of the library can be customized thanks to unsafe trait implementations.
• Tries to be convenient to use. Nobody is going to use a library that requires you to browse the documentation for hours for every single operation.

Note that vulkano does not require you to install the official Vulkan SDK. This is not something specific to vulkano (you don't need to SDK to write program that use Vulkan, even without vulkano), but many people are unaware of that and install the SDK thinking that it is required.

Development status

Vulkano is still in heavy development and doesn't yet meet its goals of being very robust. However the general structure of the library is most likely definitive, and all future breaking changes will likely be straight-forward to fix in user code.

Documentation

To get started you are encouraged to read the examples in the vulkano-examples repository, starting with the triangle example.

Structure

This repository contains six libraries:

• vulkano is the main one.
• vulkano-shaders can analyse SPIR-V shaders at compile-time.
• vulkano-shader-derive provides a custom derive that invokes vulkano-shaders. It lets you easily integrate your GLSL shaders within the rest of your source code.
• vulkano-win provides a safe link between vulkano and the winit library which can create a window to render to.
• glsl-to-spirv can compile GLSL to SPIR-V by wrapping around glslang. glsl-to-spirv is an implementation detail that you don't need to use manually if you use vulkano.
• vk-sys contains raw bindings for Vulkan. You can use it even if you don't care about vulkano.

Once procedural macros are stabilized in Rust, the vulkano-shaders and vulkano-shader-derive crates will be merged with the vulkano crate. The glsl-to-spirv crate is an implementation detail of vulkano and is not supposed to be used directly if you use vulkano. You are, however, free to use it if you want to write an alternative to vulkano.

In order to run tests, run cargo test --all at the root of the repository. Make sure your Vulkan driver is up to date before doing so.
