Traits

Traits in Rust define behaviors that are shared among different data types. Implementing traits for data types is a great way to group method signatures together and define a set of behaviors your types require. Essentially, anything with a certain trait applied to it will "inherit" the behavior of that trait's methods, but this is not the same thing as inheritance found in object-oriented programming languages.

Traits are abstract; it's not possible to create instances of traits. However, we can define pointers of trait types, and these can hold any data type that implements the trait. A trait is implemented for something else with the syntax impl TraitAbc for Xyz {...}, which can be a concrete type or another trait.
