I've been trying to learn how to use the cmd function for rust & redis, what do I pass into "con: &mut redis::Connection" to be able to successfully call fn do_something?
pub fn do_something(con: &mut redis::Connection) -> redis::RedisResult<()>
let _ : () = redis::cmd("SET").arg("my_key").arg(42).query(con)?;
Thanks for all the future help.
