What are advanced traits in Rust?

Advanced traits in Rust allow for more complex behaviors and abstractions, enabling features like trait bounds, associated types, and default implementations.

Can you explain trait bounds with an example?

Sure! Trait bounds specify that a generic type must implement a certain trait. For example, fn print<T: Display>(item: T) requires T to implement the Display trait.

What are associated types and how do they work?

Associated types are a way to define a placeholder type within a trait. For instance, in a trait Iterator, you might have an associated type Item that represents the type of elements the iterator yields.

How do default implementations in traits work?

Default implementations allow you to provide a method body in a trait. Types implementing the trait can use this default or override it with their own implementation.
