Destroying a shader module

Shader modules are used only for creating pipeline objects. After they are created, we can immediately destroy them, if we don't intend to use them anymore.

How to do it...

1. Use the handle of a logical device to initialize a variable of type VkDevice named logical_device.
2. Take the shader module's handle stored in a variable of type VkShaderModule named shader_module.
3. Call vkDestroyShaderModule( logical_device, shader_module, nullptr ) providing the logical_device variable, the shader_module variable, and a nullptr value.
4. Assign a VK_NULL_HANDLE value to the shader_module variable for safety reasons.

How it works...

Shader modules are used only during the pipeline creation. They are provided as part of a shader stages state. When pipelines that use given modules are already created, we can destroy the modules (immediately after the pipeline creating functions have finished), as they are not needed for the pipeline objects to be correctly used by the driver.
