Creating a pipeline layout with a combined image sampler, a buffer, and push constant ranges

We know how to create descriptor set layouts and use them to create a pipeline layout. Here, in this sample recipe, we will have a look at how to create a specific pipeline layout--one which allows a pipeline to access a combined image sampler, a uniform buffer, and a selected number of push constant ranges.

How to do it...

1. Take the handle of a logical device and store it in a variable of type VkDevice named logical_device.
2. Create a variable of type std::vector<VkDescriptorSetLayoutBinding> named descriptor_set_layout_bindings.
3. Add a new element to the descriptor_set_layout_bindings vector and use the following values to initialize its members:
   • 0 value for binding.
   • VK_DESCRIPTOR_TYPE_SAMPLED_IMAGE value for descriptorType.
   • 1 value for descriptorCount.
   • VK_SHADER_STAGE_FRAGMENT_BIT value for stageFlags.
   • nullptr value for pImmutableSamplers.
4. Add a second member to the descriptor_set_layout_bindings vector...
