Example Concept: Rust's ownership model is based on three main rules: each value has a single owner, ownership can be transferred (moved), and data can be borrowed either mutably or immutably. The borrow checker enforces these rules at compile time, ensuring that data races are impossible by preventing simultaneous mutable access to shared data. This compile-time safety eliminates the need for runtime checks and garbage collection, leading to more predictable performance and safer concurrent code.
