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. + +## Further information + +- [Traits](https://doc.rust-lang.org/book/ch10-02-traits.html) |
