Struct VkBufferHandle 

pub struct VkBufferHandle { /* private fields */ }

Vulkan VkBuffer on a specific VkDevice.

Implementations

impl VkBufferHandle

pub unsafe fn try_from_raw( buffer: u64, device: *mut c_void, uuid: Option<[u8; 16]>, size: u64, keep_alive: Option<KeepAlive>, ) -> Result<Self, InvalidHandleError>

Wrap a raw VkBuffer and its device parentage. Borrowing: the handle is stored non-owningly, this type has no Drop, and every obligation below extends to each Clone.

Safety

• buffer must be a live VkBuffer handle on device. As with VkImage::try_from_raw, only the zero handle is rejected (InvalidHandleError::NullHandle); everything else is stored verbatim and later used in vkCmdCopyBuffer / vkGetBufferMemoryRequirements by the importer.
• device == null is permitted and carries the same trusted-import meaning as on VkImage::try_from_raw; when non-null it must be the VkDevice buffer was created on.
• uuid, when Some, must equal that device’s physical device deviceUUID, for the same cross-adapter refusal check.
• size must not exceed the buffer’s actual VkBufferCreateInfo::size — importers copy size bytes out of it. A zero size is rejected as InvalidHandleError::ZeroSize and is therefore not a caller obligation.
• Lifetime and thread affinity are exactly as for VkImage::try_from_raw: nothing is retained, there is no Drop, and vkDestroyBuffer must not run while this value or any Clone of it is reachable.
