Rust Programming Tutorial #28 - Defining Traits
Similar to interfaces in other languages, traits allow you to set 'rules' or 'requirements' for a particular struct in order for it to be considered to be 'something'.
In this video we create a trait called 'HasVoiceBox' which says that any Struct implementing this trait must have a speak() and can_speak() method defined on it.
