7/// Use the macro `VkSubpassDescriptionFlags!` as an alternative method to create a structure. For example, these two snippets return the same value:
8/// ```
9/// VkSubpassDescriptionFlags!(per_view_attributes_nvx, per_view_position_x_only_nvx)
10/// ```
11/// ```
12/// VkSubpassDescriptionFlags {
13///     per_view_attributes_nvx: true,
14///     per_view_position_x_only_nvx: true,
15/// }
