Class Documentation

class VulkanDescriptorSetManager : public portal::renderer::DescriptorSetManager

Vulkan descriptor set manager with automatic invalidation tracking.

Binds resources to shader descriptor sets by name using shader reflection. Manages descriptor allocation, updates, and multi-buffering.

Public Functions
