Rust's Ownership System: Preventing Memory Errors at Compile Time

Rust prevents memory management errors at compile time through its ownership system and RAII (Resource Acquisition Is Initialization). Each value has only one owner; ownership can be moved between variables, but a given object cannot be mutably referenced in more than one place at a time. Example code demonstrates ownership transfer: after the ownership of variable `a` is moved to `_b`, accessing `a` again results in a compile-time error, ensuring memory safety. This contrasts with traditional garbage collection; Rust guarantees memory safety through compile-time checks, resulting in improved performance and reliability.
