Rust 101 - 12: Traits

Explaining what a trait is, and how to use it. A trait is a bit like an Interface in Java or Go, or an Abstract Base Class in C++ or Python, but it can be used to define behaviour at compile-time as well as at run-time. We go through an example of why you might want to write a "generic" function - one that works for lots of different types, and if so, how you need to be able to say what the types can do if you want to write the body of the function. Traits are a way of saying what a type can do.
