Rust: safe and concurrent. But how does it do it?
summary
Rust enforces memory safety and race-free concurrency without a garbage collector by applying ownership rules at compile time and using zero-cost abstractions. It explains the ownership and borrow checker, lifetimes and Drop for deterministic cleanup, and the smart pointers Box, Rc and Arc for heap allocation and safe shared ownership, showing how the compiler rejects unsafe moves, mutable-vs-immutable aliasing, and unsafe concurrent reference counting to prevent data races.
