Struct ExternalMemory 

pub struct ExternalMemory { /* private fields */ }

An imported external-memory handle (Vulkan VkDeviceMemory, D3D12 heap / resource, NvSciBuf, DMA-buf FD, …). Destroyed on drop.

Implementations

impl ExternalMemory

pub unsafe fn import(desc: &CUDA_EXTERNAL_MEMORY_HANDLE_DESC) -> Result<Self>

Import an external-memory handle described by desc.

Safety

desc.handle must describe a live OS object that the process can access (file descriptor, NT HANDLE, NvSciBufObj, …). CUDA retains a reference to the underlying memory until this ExternalMemory drops.

pub fn mapped_buffer( &self, offset: u64, size: u64, flags: u32, ) -> Result<*mut c_void>

Expose a subregion of the imported memory as a device pointer valid in the current CUDA context.

pub fn as_raw(&self) -> cudaExternalMemory_t

Raw handle. Interchangeable with CUexternalMemory at the ABI level — cast via as baracuda_cuda_sys::CUexternalMemory if you need to interop with the Driver-side wrapper.

Trait Implementations

impl Clone for ExternalMemory

fn clone(&self) -> ExternalMemory

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ExternalMemory

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
