6///
7/// Use the macro `VkExternalSemaphoreFeatureFlags!` as an alternative method to create a structure. For example, these two snippets return the same value:
8/// ```
9/// VkExternalSemaphoreFeatureFlags!(exportable, importable)
10/// ```
11/// ```
12/// VkExternalSemaphoreFeatureFlags {
13///     exportable: true,
14///     importable: true,
15/// }
16/// ```
