There are a number of text conventions used throughout this book.

Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: “For each resource type, we call the relative method on the DescriptorSetCreation object.”

A block of code is set as follows:

export VULKAN_SDK=~/vulkan/1.2.198.1/x86_64 
export PATH=$VULKAN_SDK/bin:$PATH 
export LD_LIBRARY_PATH=$VULKAN_SDK/lib:$LD_LIBRARY_PATH 
export VK_LAYER_PATH=$VULKAN_SDK/etc/vulkan/explicit_layer.d

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

VkPhysicalDeviceFeatures2 device_features{ VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_FEATURES_2, &indexing_features }; 
    vkGetPhysicalDeviceFeatures2( vulkan_physical_device, 
    &device_features ); 
    bindless_supported = indexing_features.
    descriptorBindingPartiallyBound && indexing_features.
    runtimeDescriptorArray;

Any command-line input or output is written as follows:

$ tar -xvf vulkansdk-linux-x86_64-1.2.198.1.tar.gz

Bold: Indicates a new term, an important word, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “We then start the application by clicking on Launch, and we will notice an overlay reporting the frame time and the number of frames rendered.”
