Rust Ownership Explained - Move, Clone, Borrow & References | Memory Safety Tutorial

Master Rust's ownership system! Learn how Rust achieves memory safety without garbage collection through ownership rules, move semantics, and borrowing. 📚 What You'll Learn: • The two ownership rules in Rust • Move semantics - when values transfer ownership • Clone - explicitly copying heap data • Copy - automatic copying for stack types • References and borrowing • Mutable references 💻 Code Examples: 1. Move Semantics: let s1 = String::from("hello"); let s2 = s1; println!("s2 = {}", s2); 2. Clone for Deep Copy: let s1 = String::from("hello"); let s2 = s1.clone(); println!("s1 = {}", s1); println!("s2 = {}", s2); 3. References (Borrowing): fn calculate_length(s: ref String) { s.len() } 🔑 Key Concepts: • Each value has exactly one owner • When owner goes out of scope, value is dropped • Move transfers ownership for heap data • Clone creates independent copies • Copy is automatic for stack types like integers • ref borrows without taking ownership • ref mut allows mutable borrowing Created by Celeste ✨ #Rust #RustLang #Programming #Ownership #MemorySafety #Tutorial #Borrowing #Beginner
