Detailed Description

Represents a Vulkan shader, managing modules, reflection data, and descriptor sets.

Loads and compiles Vulkan shaders from file, holds SPIR-V binaries, reflection data (uniforms, resources), descriptor set layouts, and Vulkan descriptor sets.

Constructor & Destructor Documentation

VulkanShader()

Raven::VulkanShader::VulkanShader	(	const std::string &	filepath,
