Function cuvsCagraSerializeToHnswlib 

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

Save the CAGRA index to file in hnswlib format. NOTE: The saved index can only be read by the hnswlib wrapper in cuVS, as the serialization format is not compatible with the original hnswlib.

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