I’m doing the Rust track and am currently on the Redis challenge. It appears we’re not able to modify Cargo.toml to add community crates? I found the ‘polling’ crate which could help implement and event loop in #ZU2 of the challenge, but I guess that’s a no-go?

You should be able to modify Cargo.toml now 
We shipped support for this a while back but haven’t gotten around to removing the warnings yet – will do as part of our next Rust upgrade!
Amazing! Shall give it a try.
Ok, the polling crate is out…means unsafe Rust, which I’m not up for. Back to the proverbial drawing board!
