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

To fix the error [E0106]: missing lifetime specifier, you need to add a lifetime parameter to the function signature. Here's an example:

fn dangle<'a>() -> &'a String {
    // function body
}

By adding the 'a lifetime parameter, you specify that the returned reference should have a lifetime that is connected to the input lifetime 'a. This allows the Rust compiler to correctly determine the lifetimes of references in your code.

Please note that the specific lifetime parameter you choose ('a in this example) may depend on your specific code and requirements.
