Enum BufferOwnership 

enum BufferOwnership {
    Managed(Mutex<BufferMemoryBacking>),
    RawHandle,
    External(DropGuard),
}

Available on vulkan only.

Describes who owns a Buffer’s vk::Buffer handle and its backing memory, and therefore what cleanup is required when the buffer is destroyed.

Variants

Managed(Mutex<BufferMemoryBacking>)

wgpu-hal owns the vk::Buffer and its backing memory. On cleanup the buffer handle is destroyed and the memory is released.

RawHandle

wgpu-hal owns the vk::Buffer handle but the backing memory is kept alive by the caller. On cleanup only the buffer handle is destroyed.

External(DropGuard)

Caller owns the vk::Buffer and its backing memory. On cleanup the crate::DropGuard runs the caller’s cleanup callback and wgpu-hal touches neither the handle nor the memory.
