Literal string

---

• The variable "name" points to a literal string. (aka. hard-coded string). The string can never change.
• Because the variable is not mutable, we cannot even replace the content. (See error message generated by the commented out code.)

examples/ownership/literal-string/src/main.rs

fn main() {
    let name = "Foo";
    let other = name;
    println!("{name}");
    println!("{other}");

    //name = "Foo Bar";

    println!("{name}");
    println!("{other}");
}

Foo
