-The program will connect using an application-specific definition of the space. The program will open a socket connection with the Tarantool server at localhost:3301, then send an INSERT request, then — if all is well — end without saying anything. If Tarantool is not running on localhost with listen port = 3301, or if user guest does not have authorization to connect, or if the insert request fails for any reason, the program will print an error message, among other things (stacktrace, etc).

 The example program only shows one request and does not show all that’s necessary for good practice. For that, please see the [progaudi.tarantool](https://github.com/progaudi/progaudi.tarantool) driver repository.
