In the Rust compiler, a pull request is being considered (see GitHub PR rust-lang/rust#41336) that will add support for a |= &b (instead of only a |= b) for numeric types like u64. Unfortunately, this breaks the build of vulkano, because vulkano currently does the following in pipeline_barrier.rs: self.src_stage_mask |= source.into(); self.dst_stage_mask |= dest.into(); Rust is currently able to infer that the result of source.into() must be a vk::PipelineStageFlags, because it gets bitor-ed to one. But if the PR on the compiler is accepted, this type inference will no longer be possible, because the return value of source.into() might then also be &'a vk::PipelineStageFlags for some lifetime 'a. This commit specifies the output type of the conversion explicitly, so that it doesn't require any type inference. |

Vulkano
Note: requires Rust 1.9. This library would highly benefit from multiple upcoming features in Rust. Therefore it is likely that in the future you will need to update your version of Rust to continue using vulkano.
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 draw a teapot, but to cover all possible usages of Vulkan and detect all the possible problems. Invalid API usage is prevented thanks to both compile-time checks and runtime checks.
- Handles synchronization on the GPU side for you, 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.
Warning: this library breaks every five minutes for the moment.
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.
Documentation
To get started you are encouraged to read the examples in examples/src/bin, starting with
the triangle example.
Structure
This repository contains four libraries:
vulkanois the main one.vulkano-shaderscan analyse SPIR-V shaders at compile-time.vulkano-winprovides a safe link between vulkano and thewinitlibrary which can create a window where to render to.glsl-to-spirvcan compile GLSL to SPIR-V by wrapping aroundglslang.glsl-to-spirvis an implementation detail that you don't need to use manually if you use vulkano.
Once procedural macros are stabilized in Rust, the vulkano-shaders crate 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.
This crate uses the Cargo workspaces feature that is available only in nightly, and whose purpose
is to make several crates share the same target/ directory. It is normal to get an error if you
try to run cargo build at the root of the directory.
In order to run tests, go to the vulkano subdirectory and run cargo test. Make sure your
Vulkan driver is up to date before doing so.
