A Better Person

Explore the use of owned String values in Rust structs to handle names efficiently and avoid lifetime complexities with string references. Understand the trade-offs in memory and performance when transitioning from string literals to owned strings, and practice by creating and managing Person instances with dynamic string data.

We'll cover the following...

Rust 1.40.0
struct Person {
    name: &'static str,
