Struct VulkanHost 

#[non_exhaustive]
pub struct VulkanHost {
    pub api_version: VulkanVersion,
}

The host’s Vulkan runtime.

Reported from the loader and the installed ICD manifests, so — unlike RocmHost and OneApiHost — this describes a runtime that is actually present rather than a toolkit that may be. There is no architecture field: SPIR-V is portable and driver-compiled, so a Vulkan build has no per-GPU target to match.

Host-level, not per-device: see api_version for what the number does and does not promise.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

api_version: VulkanVersion

Highest API version any installed driver advertises in its ICD manifest.

A driver’s own static declaration on disk, which makes it two things it is easy to mistake it for:

• Not per-device. With two drivers installed — an AMD iGPU beside an NVIDIA dGPU, say — this is the higher of the two and may describe neither card. A specific device’s version comes from vkGetPhysicalDeviceProperties, which means linking the loader and creating an instance; this crate deliberately does neither.
• Not the loader’s instance version. That is what vulkaninfo and vkEnumerateInstanceVersion report, and it is usually the newer of the two, so the numbers routinely disagree. The driver’s is the one that binds in practice: loaders track the current headers while drivers implement features on their own schedule.

Compare on major/minor only — see VulkanVersion.
