These are raw notes taken at RustConf during the “Traits and Threads” workshop put on by Aaron Turon All Exercises Methods are function that accept self &self.items == &(self.items) where the borrow (&) is for the item, not for self. Structs have no default value, requires creating all values. mut as mute not like a mixed breed dog Abstraction: The Plan Generics Traits As Interfaces For Code Resuse For Perator Overloading Trait Objects Traits are rusts interfaces.
It started with Muxed. I was excited to get a working first build, but despite my development machine being a MacBook Air, I develop most in VM’s using vagrant. My native builds were all linux based. It would be easy enough to move the code to an OSX machine and compile there but I do not like build tools on my native machine. And that would simply be too easy.
DelayedJob has always been a great “hit the ground running” background task runner for ruby. It is simple to setup, easy to use and can more than carry its own weight in tasks. Don’t know what a backround runner does or why you would use one? I will not delve into why you need one but you can check out a summary here: Background Jobs in Ruby on Rails.

I have used the asset pipeline heavily since its release in Rails 3.1.0 over two years ago. Only recently did I run in to a handful of gotchas when it came to dealing with stylesheet compilations using Sass. error: cannot access named params by position error: cannot access named params by position I guest wrote a post about my experience using SASS in the asset pipeline at Unbounce.
