Mostly safe Vulkan library for Rust.
- Version: 0.3.2
- Supported Vulkan specification: 1.0.8
Development is active and ongoing. Support for new Vulkan revisions will be added one-by-one. New extensions will also be supported along the way.
Dacite is sorely lacking in the documentation department. I don't plan to fully document every type and function (and thus effectively repeat the Vulkan specification). But at least the parts where dacite is different from the C API will be documented over time.
Rust 1.18.0 or newer is required.
Dacite is available on crates.io. Add this to your
 = "0.3"
Check out the examples subdirectory to get started.
The Vulkan library (or more specifically, the Vulkan icd loader) is loaded dynamically at runtime. This means, that development with dacite works out-of-the-box, without installing anything else (like C headers or the LunarG Vulkan SDK on Windows).
Dacite uses vks as its Vulkan FFI bindings and symbol loader.
Goals and Non-Goals
- Map the whole Vulkan API almost one-to-one to equivalent Rust types and functions, unless there is a good reason not to.
- Support multi-threaded usage.
- Don't hide the flexibility and complexity of Vulkan.
- Don't reimplement the validation layers: valid usage is not checked, but assumed.
Completeness and a simple mapping between the C and Rust API are probably the most important goals. As such, most of dacites responsibility lies in converting the provided Rust types to and from their C counterparts.
The Vulkan specification is very strict about what constitutes valid usage and what doesn't. The general rule is, that invalid usage results in undefined behaviour. Dacite does not in any way enforce valid API usage by its design.
I strongly suggest to check out the vulkano project, if dacite doesn't suit your requirements.
Dacite is safe, as long as it is used according to the Vulkan specification. However, invalid usage will result in undefined behaviour. Enabling the validation layers during development is a good way to prevent bad things from happening. Dacite does very little on its own in this regard.
One exception to this rule is, that the lifetime of an object is bound to its direct parent object
(dynamically, via reference counting) from which it was created. For example, an
Image will always
outlive its parent
Device. However, other dependencies are not modelled. For instance, binding
DeviceMemory to a
Buffer, will not ensure, that the
DeviceMemory outlives the
The same is true for essentially all such relationships in the Vulkan API.
Dacite follows the Semantic Versioning scheme. Although the current version is still below 1.0.0, the minor version component will be incremented whenever breaking changes are made. Version 1.0.0 will not be released, before dacite supports the most recent Vulkan revision and all extensions.
The main source of breaking API changes are new Vulkan extensions. More specifically, new variants added to an existing enum by a new extension must be considered a breaking change.
Dacites has been designed such, that all other additions by new extensions should not break existing applications. However, the development of vks has shown, that many Vulkan revisions contain minor mistakes, which are then fixed later. If one of these mistakes makes it into dacite, its removal might be breaking change.
