What are traits and trait objects in Rust?
An example of an AI chatbot conversation about Rust traits and trait objects.
Can you explain what traits are in Rust?
Sure! Traits in Rust are a way to define shared behavior. They allow you to specify a set of methods that types must implement.
What about trait objects? How do they differ from regular traits?
Trait objects allow for dynamic dispatch, meaning you can call methods on types that implement a trait without knowing their concrete type at compile time.
Can you give me an example of using trait objects?
Absolutely! You can use a trait object like this: fn print_shape(shape: &dyn Shape) { shape.draw(); } where Shape is a trait.
Are there any performance implications when using trait objects?
Yes, using trait objects can introduce a slight overhead due to dynamic dispatch, but it offers flexibility in your code.
