erupt

Vulkan API bindings

Take a look at the erupt user guide.

MAINTENANCE MODE NOTICE

It is not recommended to use erupt for new projects, use ash instead. There is work underway to rewrite ash using ideas from the erupt project, for updates see https://github.com/ash-rs/ash/issues/344. Simple patches to erupt will still be merged, but no large changes are to be expected.

Features

• Full Vulkan API coverage
• First-class support for all extensions
• High quality auto-generated function wrappers
• A utility module aiding your use of this crate
  • VulkanResult: Idiomatic wrapper around a Vulkan Result
  • surface: Create a SurfaceKHR using a RawWindowHandle (adapted from ash-window)
• Generated code distributed into multiple modules
• Function loading (EntryLoader, InstanceLoader, DeviceLoader)
• Separate Flags and FlagBits types
• A high level Builder for every struct
• Type-safe pointer chain support
• Default and Debug implementation for every type
• Confirmed support for Linux, Windows, macOS and Android
• Complete auto-generation of everything except utils

Example: Instance Creation

use erupt::{vk, EntryLoader, InstanceLoader};

let entry = EntryLoader::new()?;

let app_info = vk::ApplicationInfoBuilder::new()
    .api_version(vk::API_VERSION_1_1);
let instance_info = vk::InstanceCreateInfoBuilder::new()
    .application_info(&app_info);
let instance = InstanceLoader::new(&entry, &instance_info)?;

// ...

instance.destroy_instance(None);

Cargo Features

• surface (enabled by default): Enables the surface module, adds raw-window-handle dependency
• loading (enabled by default): Enables the EntryLoader::new function, adds libloading dependency
• bytemuck: Implements Pod for some hand-picked structs (*IndirectCommand, etc.), adds bytemuck dependency

FAQ

Q: What's the difference between this, ash and vulkano?

A: Vulkano is special because it provides hand-written Vulkan wrappers, which means that for example it has a special hand-written wrapper around a Vulkan PhysicalDevice. On the other hand ash and erupt both provide Vulkan API bindings too, but not exposing such fancy wrappers and instead focusing on having good bindings to the raw Vulkan API.

The big selling points of erupt is that it has better documentation, high level function support for all extensions (which is only really relevant if you use those extensions), being fully generated and some more smaller improvements. On the other hand ash has a bigger existing community.

Q: What does the number at the end of the version mean?

A: It represents the Vulkan Header version this version of erupt was generated against and is purely informational.
