🔑Smart pointers and interior mutability are important concepts in Rust.
🔒Smart pointers like ARC and RC provide shared ownership of a value.
🔑Ref cell and mutex cell provide interior mutability in a controlled and safe manner.
🔒Deref and asref traits are used to convert a value into a reference.
🔑The borrow trait is used to enforce borrowing rules at compile-time.
What are smart pointers in Rust?
—Smart pointers are types that provide additional functionality and safety guarantees beyond regular references.
What is interior mutability?
—Interior mutability is a concept that allows for the mutation of a value even when it is considered immutable by the type system.
When should I use smart pointers in Rust?
—You should use smart pointers when you need shared ownership, interior mutability, or additional functionality not provided by regular references.
How do smart pointers ensure memory safety?
—Smart pointers use ownership and borrowing rules enforced by the Rust compiler to prevent common memory errors like use-after-free and data races.
What are the advantages of using interior mutability in Rust?
—Interior mutability allows for more flexible and ergonomic code without sacrificing memory safety, as it enforces borrowing rules at compile-time.
