Module dot 

cudaGraphDebugDotPrint round-trip — emit a Graphviz DOT file describing a captured graph for tooling / visualisation.

cudarc’s cuGraphDebugDotPrint writes the DOT to a file path, not a buffer. We use a temporary file under std::env::temp_dir() and read the contents back as a String.

Structs
