VkSemaphoreType

Possible values of VkSemaphoreTypeCreateInfo::semaphoreType, specifying the type of a semaphore, are:

typedef enum VkSemaphoreType {
    VK_SEMAPHORE_TYPE_BINARY = 0,
    VK_SEMAPHORE_TYPE_TIMELINE = 1,
} VkSemaphoreType;

pub struct SemaphoreType(u32);
impl SemaphoreType {
    pub const BINARY: Self = 0;
    pub const TIMELINE: Self = 1;
}

#define VkSemaphoreTypeKHR VkSemaphoreType

const SemaphoreTypeKHR: _ = vk::SemaphoreType;

• VK_SEMAPHORE_TYPE_BINARY specifies a binary semaphore type that has a boolean payload indicating whether the semaphore is currently signaled or unsignaled. When created, the semaphore is in the unsignaled state.
• VK_SEMAPHORE_TYPE_TIMELINE specifies a timeline semaphore type that has a strictly increasing 64-bit unsigned integer payload indicating whether the semaphore is signaled with respect to a particular reference value. When created, the semaphore payload has the value given by the initialValue field of VkSemaphoreTypeCreateInfo.
