VkCopyAccelerationStructureModeKHR

Possible values of mode specifying additional operations to perform during the copy, are:

typedef enum VkCopyAccelerationStructureModeKHR {
    VK_COPY_ACCELERATION_STRUCTURE_MODE_CLONE_KHR = 0,
    VK_COPY_ACCELERATION_STRUCTURE_MODE_COMPACT_KHR = 1,
    // Provided by extensions
    VK_COPY_ACCELERATION_STRUCTURE_MODE_SERIALIZE_KHR = 2,
    VK_COPY_ACCELERATION_STRUCTURE_MODE_DESERIALIZE_KHR = 3,
    VK_COPY_ACCELERATION_STRUCTURE_MODE_CLONE_NV = VK_COPY_ACCELERATION_STRUCTURE_MODE_CLONE_KHR,
    VK_COPY_ACCELERATION_STRUCTURE_MODE_COMPACT_NV = VK_COPY_ACCELERATION_STRUCTURE_MODE_COMPACT_KHR,
} VkCopyAccelerationStructureModeKHR;

pub struct CopyAccelerationStructureModeKHR(u32);
impl CopyAccelerationStructureModeKHR {
    pub const CLONE: Self = 0;
    pub const COMPACT: Self = 1;
    pub const SERIALIZE: Self = 2;
    pub const DESERIALIZE: Self = 3;
    pub const CLONE_NV: Self = Self::CLONE;
    pub const COMPACT_NV: Self = Self::COMPACT;
}

#define VkCopyAccelerationStructureModeNV VkCopyAccelerationStructureModeKHR

const CopyAccelerationStructureModeNV: _ = vk::CopyAccelerationStructureModeKHR;

• VK_COPY_ACCELERATION_STRUCTURE_MODE_CLONE_KHR creates a direct copy of the acceleration structure specified in src into the one specified by dst. The dst acceleration structure must have been created with the same parameters as src. If src contains references to other acceleration structures, dst will reference the same acceleration structures.
• VK_COPY_ACCELERATION_STRUCTURE_MODE_COMPACT_KHR creates a more compact version of an acceleration structure src into dst. The acceleration structure dst must have been created with a size at least as large as that returned by vkCmdWriteAccelerationStructuresPropertiesNV , vkCmdWriteAccelerationStructuresPropertiesKHR, or vkWriteAccelerationStructuresPropertiesKHR after the build of the acceleration structure specified by src. If src contains references to other acceleration structures, dst will reference the same acceleration structures.
• VK_COPY_ACCELERATION_STRUCTURE_MODE_SERIALIZE_KHR serializes the acceleration structure to a semi-opaque format which can be reloaded on a compatible implementation.
• VK_COPY_ACCELERATION_STRUCTURE_MODE_DESERIALIZE_KHR deserializes the semi-opaque serialization format in the buffer to the acceleration structure.
