What is ownership in Rust?

What is ownership in Rust?

Ownership in Rust is a set of rules that governs how memory is managed. It ensures memory safety without a garbage collector.

Can you explain the three main rules of ownership?

Sure! The three main rules are: 1) Each value in Rust has a variable that’s its owner. 2) A value can only have one owner at a time. 3) When the owner goes out of scope, the value will be dropped.

What happens if I try to use a value after its owner has gone out of scope?

If you try to use a value after its owner has gone out of scope, Rust will throw a compile-time error to prevent potential memory issues.

How does borrowing work in Rust?

Borrowing allows you to use a value without taking ownership. You can have either one mutable reference or multiple immutable references at a time.
