This is the demo code from Rust Melbourne's second event on 2016-09-20.
http://www.meetup.com/Rust-Melbourne/events/233345740/
I've only had this successfully running against rustc version nightly-2016-08-18. It's a little bit hard to find a working version that works with recent version of both serde and diesel at the moment.
To run this...
./make_database.sh
rustup override set nightly-2016-08-18
cargo run
