Code

fn main() {
    let s1 = String::from("hello");

    // println!("{}", s1); // error: value borrowed after move
    println!("{}", s2);
}

Explanation

This example demonstrates how to use ownership basics in Rust. Read the code carefully to understand the flow. Pay attention to where values are created, borrowed, moved, or consumed.

Key Concepts

• Rust's strong type system catches errors at compile time
• Ownership and borrowing rules ensure memory safety
