13. Memory management 🦀
14. Memory management styles • Manually allocate / free memory (seg fault / double free) • Garbage Collector (Ruby, Python, Golang, Java, Erlang, c) • Ownership / Borrowing (Rust only as far as I know)
15. Rust brings to language design and compile time the memory management By using Ownership and Borrowing
16. Ownership Rules 1. Each value in Rust is owned by variable. 2. When the owner goes out of scope, the value will be deallocated. 3. There can be Only ONE owner at a time.
17. 1. Each value in rust is owned by a variable

19. 2. When the owner goes out of scope the value will deallocated
