Detailed Description

A generic platform Vulkan instance implementation.

Since
5.10

Implements QPlatformVulkanInstance, serving as a base for platform-specific implementations. The library loading and any WSI-specifics are excluded.

Subclasses are expected to call init() from their constructor and initInstance() from their createOrAdoptInstance() implementation.
