### 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 `{}`), and
|
||||||
|
+ `Debug` (which allows formatted display via `{:?}`).
|
||||||
|
|
||||||
|
Because traits indicate shared behavior between data types, they are useful when writing generics.
