What are advanced traits in Rust?
Advanced traits in Rust allow for more complex behaviors and functionalities, such as associated types and trait bounds.
Can you explain associated types with an example?
Sure! Associated types let you define a placeholder type within a trait. For example, in a trait Iterator
, you might have an associated type Item
that represents the type of elements the iterator yields.
How do trait bounds work in Rust?
Trait bounds specify that a generic type must implement a certain trait. For instance, fn process<T: Display>(item: T)
means T
must implement the Display
trait.
What are some common use cases for advanced traits?
Common use cases include creating flexible APIs, implementing polymorphism, and defining complex data structures.
