Ownership and Borrowing

Ownership Rules:

// Rule 1: Each value has one owner
let s1 = String::from("hello");
let s2 = s1; // s1 is moved, no longer valid
// println!("{}", s1); // ERROR: s1 moved

// Rule 2: When owner goes out of scope, value is dropped
{
    let s = String::from("hello");
} // s is dropped here
