Struct CapturedCudaGraph 

pub struct CapturedCudaGraph { /* private fields */ }

Instantiated CUDA Graph with owned graph + exec handles.

Implementations

impl CapturedCudaGraph

pub fn capture_on_stream<F>(stream: &CudaStream, record: F) -> Result<Self>

where F: FnOnce() -> Result<()>,

Capture work submitted by record on stream, instantiate it, and take ownership of the resulting graph handles.

pub fn launch(&self, stream: &CudaStream) -> Result<()>

Replay the instantiated graph on stream.

pub fn node_count(&self) -> Result<usize>

Number of nodes in the captured graph. Used by bounded CSM CUDA Graph cache-key and node-inventory certs to prove topology stability.

pub fn nodes(&self) -> Result<Vec<CudaGraphNode>>

Return graph nodes in CUDA’s captured graph order with their node type.

pub fn kernel_node_params( &self, node: CudaGraphNode, ) -> Result<CUDA_KERNEL_NODE_PARAMS>

Read CUDA’s raw kernel-node params for inventory/update code.

The returned kernelParams pointer is CUDA-owned capture metadata. Treat it as read-only unless constructing a fresh params object for Self::set_kernel_node_params.

pub unsafe fn set_kernel_node_params( &self, node: CudaGraphNode, params: &CUDA_KERNEL_NODE_PARAMS, ) -> Result<()>

Update a kernel node in the instantiated graph.

Safety

CUDA requires the replacement params to be topology-compatible with the captured node. The caller must keep every pointed-to kernel argument alive until CUDA has consumed the update and launched work that uses it.

pub fn memset_node_params( &self, node: CudaGraphNode, ) -> Result<CUDA_MEMSET_NODE_PARAMS>

Read CUDA’s raw memset-node params for inventory/update code.

pub fn set_memset_node_params( &self, node: CudaGraphNode, params: &CUDA_MEMSET_NODE_PARAMS, stream: &CudaStream, ) -> Result<()>

Update a memset node in the instantiated graph.

pub fn graph(&self) -> CUgraph

Raw graph handle for low-level node inventory/update code.

pub fn exec(&self) -> CUgraphExec

Raw instantiated graph handle for low-level graph-exec update code.
