@avelanarius hello, if you have someone in your team who can review Rust code and can have a quick look - it'd be awesome to cleanup any not recommended code out of this example (so people won't repeat my rust rookie mistakes)

[guy9]

I'll go ahead and merge this since we are sending a link to this lab on ScyllaDB U. to the LIVE event attendees today. @avelanarius please still review the code
