-# Traits
-
-A trait is a collection of methods.
-
-Data types can implement traits. To do so, the methods making up the trait are defined for the data type. For example, the `String` data type implements the `From<&str>` trait. This allows a user to write `String::from("hello")`.
-
-In this way, traits are somewhat similar to Java interfaces and C++ abstract classes.
-
-Some additional common Rust traits include:
-
-- `Clone` (the `clone` method)
-- `Display` (which allows formatted display via `{}`)
-- `Debug` (which allows formatted display via `{:?}`)
-
-Because traits indicate shared behavior between data types, they are useful when writing generics.
