Gentle practical introduction to Rust

Simple Rust project, incrementally growing.

Check out intermediate git commits to see the program grow:

1. Hello world
2. Introduction to common Rust language patterns
3. A regular expression parser (see https://github.com/stefan-kaestle/code4fun-rust for a simple performance comparison with Java and Python)
4. A REST API server that exposes this in the browser via json
5. A database backend, fetching data from a mysql server

Finally, a web-server (with actix) using a mysql database as backend (with diesel).

For participants of the Code4Fun, there is still a mysql server up and running (and will be for a while longer):

echo DATABASE_URL="mysql://rustuser:\%[email protected]/rustdemo" > .env

Otherwise, you can also setup your own. The working set can be downloaded from:
