What are ownership and traits in Rust?

Can you explain ownership in Rust?

Ownership in Rust is a set of rules that governs how memory is managed. Each value in Rust has a single owner, and when the owner goes out of scope, the value is dropped.

What happens if I try to use a value after its owner is dropped?

If you try to use a value after its owner has been dropped, you'll encounter a compile-time error. Rust ensures memory safety by enforcing these rules.

What are traits in Rust?

Traits in Rust are a way to define shared behavior. They allow you to specify functionality that types must implement, enabling polymorphism.

Can you give an example of a trait?

Sure! A common trait is Clone, which requires implementing a method to create a copy of an object. Types that implement Clone can be duplicated.
