Safe and rich Rust wrapper around the Vulkan API.
Brief summary of Vulkan
Instanceobject is the API entry point. It is the first object you must create before starting to use Vulkan.
PhysicalDeviceobject represents an implementation of Vulkan available on the system (eg. a graphics card, a software implementation, etc.). Physical devices can be enumerated from an instance with
Once you have chosen a physical device to use, you can create a
Deviceobject from it. The
Deviceis the most important object of Vulkan, as it represents an open channel of communicaton with a physical device. You always need to have one before you can do interesting things with Vulkan.
Buffers and images can be used to store data on memory accessible by the GPU (or more generally by the Vulkan implementation). Buffers are usually used to store information about vertices, lights, etc. or arbitrary data, while images are used to store textures or multi-dimensional data.
In order to show something on the screen, you need a
Images that correspond to the content of the window or the monitor. When you present a swapchain, the content of one of these special images is shown on the screen.
In order to ask the GPU to do something, you must create a command buffer. A command buffer contains a list of commands that the GPU must perform. This can include copies between buffers and images, compute operations, or graphics operations. For the work to start, the command buffer must then be submitted to a
Queue, which is obtained when you create the
In order to be able to add a compute operation or a graphics operation to a command buffer, you need to have created a
GraphicsPipelineobject that describes the operation you want. These objects are usually created during your program's initialization.
Shaders are programs that the GPU will execute as part of a pipeline. Descriptors can be used to access the content of buffers or images from within shaders.
For graphical operations,
Framebuffers describe on which images the implementation must draw upon.
Once you have built a command buffer that contains a list of commands, submitting it to the GPU will return an object that implements the
GpuFutures allow you to chain multiple submissions together and are essential to performing multiple operations on multiple different GPU queues.
