Struct ExternalMemory 

pub struct ExternalMemory { /* private fields */ }

An imported external-memory handle (Vulkan VkDeviceMemory, D3D12 heap, NvSciBuf, …). Destroyed on drop.

Implementations

impl ExternalMemory

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

Import an external-memory handle described by desc.

Safety

desc must describe a live OS object that the calling process has permission to access — a Vulkan-exported file descriptor, a D3D12-exported NT HANDLE, etc. CUDA retains a reference to the underlying object until this ExternalMemory drops.

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

Expose a subregion of the external memory as a device pointer. The returned pointer is valid until this ExternalMemory drops.

pub fn as_raw(&self) -> CUexternalMemory

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.
