VkBuildAccelerationStructureModeKHR

The VkBuildAccelerationStructureModeKHR enumeration is defined as:

typedef enum VkBuildAccelerationStructureModeKHR {
    VK_BUILD_ACCELERATION_STRUCTURE_MODE_BUILD_KHR = 0,
    VK_BUILD_ACCELERATION_STRUCTURE_MODE_UPDATE_KHR = 1,
} VkBuildAccelerationStructureModeKHR;

pub struct BuildAccelerationStructureModeKHR(u32);
impl BuildAccelerationStructureModeKHR {
    pub const BUILD: Self = 0;
    pub const UPDATE: Self = 1;
}

• VK_BUILD_ACCELERATION_STRUCTURE_MODE_BUILD_KHR specifies that the destination acceleration structure will be built using the specified geometries.
• VK_BUILD_ACCELERATION_STRUCTURE_MODE_UPDATE_KHR specifies that the destination acceleration structure will be built using data in a source acceleration structure, updated by the specified geometries.
