Rust Borrowing Development Tutorials, Guides & Insights

Functions return the last expression without a semicolon:

fn five() -> i32 {
    5
}

• Lifetime annotations are crucial in defining how long references in structs or functions must live.
• Multiple lifetime parameters can be used to manage complex relationships between references.

In this section, we'll implement a safe and efficient linked list in Rust, utilizing the advanced memory management concepts we've covered. The linked list will demonstrate ownership, borrowing, and lifetimes in a real-world scenario, showcasing how Rust’s features can be leveraged to write safe and performant code.
