rust•armanazi•error•[E0106]: missing lifetime specifier --> src/main.rs:5:20 | 5 | fn dangle() -> &i32 { // dangle returns a reference to a String | ^ expected named lifetime parameter

rust•armanazi•error•[E0106]: missing lifetime specifier --> src/main.rs:5:16 | 5 | fn dangle() -> &String { | ^ expected named lifetime parameter

fn no_dangle() -> String {
    let s = String::from("hello");

    s
}
