Rust lets you abstract over types with traits. They're similar to interfaces:

trait Pet {
    /// Return a sentence from this pet.
    fn talk(&self) -> String;

    /// Print a string to the terminal greeting this pet.
    fn greet(&self);
}
This slide and its sub-slides should take about 10 minutes.

  • A trait defines a number of methods that types must have in order to implement the trait.

  • In the "Generics" segment, next, we will see how to build functionality that is generic over all types implementing a trait.
