Function cuvsCagraSerializeGraphAndDataset 

pub unsafe extern "C" fn cuvsCagraSerializeGraphAndDataset(
    res: cuvsResources_t,
    filename: *const c_char,
    index: cuvsCagraIndex_t,
) -> cuvsError_t

Save the CAGRA graph and its attached dataset to file.

The index stores a non-owning dataset view. The caller must keep the dataset backing that view alive while this function runs. Returns CUVS_ERROR without modifying the destination file if the index has no attached dataset.

Experimental, both the API and the serialization format are subject to change.
