Ownership and Move Semantics

Background

Ownership is Rust unique feature that guarantees memory safety without garbage collection.

Problem

Show how Rust ownership prevents use-after-free through move semantics at compile time.

Input

Variables being moved and borrowed

Output

Compile-time safety guarantees

Sample tests

Input: let s1 = String; let s2 = s1;

Expected: s1 invalid after move

Your solution
