    A Guide to Rust Syntax

A very brief guide to Rust syntax. It assumes you are already familiar with programming concepts.
This was written in 2014. It is not a good reference for Rust today,
though the content is still correct.
cheats.rs looks like a good alternative.

## websocket_tornado_redis.py
"""
This is a simple example of WebSocket + Tornado + Redis Pub/Sub usage.
Do not forget to replace YOURSERVER by the correct value.
Keep in mind that you need the *very latest* version of your web browser.
You also need to add Jacob Kristhammar's websocket implementation to Tornado:
Grab it here:
    http://gist.github.com/526746
Or clone my fork of Tornado with websocket included:
    http://github.com/pelletier/tornado
Oh and the Pub/Sub protocol is only available in Redis 2.0.0:
