What are some advanced usage patterns for traits in Rust?

In Rust, advanced usage of traits can include trait objects, associated types, and default method implementations. Would you like to explore any of these in detail?

Yes, can you explain trait objects?

Trait objects allow for dynamic dispatch, enabling you to call methods on types that implement a trait without knowing the exact type at compile time. You can create a trait object using Box<dyn TraitName>.

What about associated types?

Associated types let you define a placeholder type within a trait, which can be specified when implementing the trait. This can make your code more flexible and easier to read.

Can you give an example of default method implementations?

Sure! You can provide default implementations for methods in a trait, allowing types that implement the trait to use the default or override it. This is useful for providing common functionality.
