Lines at which warnings are generated are functions which actually return values. ``` /workspaces/cpp-msgpack-rpc/include/msgpack_rpc/clients/call_future.h:89: warning: found documented return type for msgpack_rpc::clients::CallFuture< void >::get_from_call_result that does not return anything /workspaces/cpp-msgpack-rpc/include/msgpack_rpc/clients/call_future.h:56: warning: found documented return type for msgpack_rpc::clients::CallFuture< void >::get_result that does not return anything /workspaces/cpp-msgpack-rpc/include/msgpack_rpc/clients/call_future.h:71: warning: found documented return type for msgpack_rpc::clients::CallFuture< void >::get_result_within that does not return anything ``` ## Note
