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

The error message you encountered in Rust, specifically the rust•armanazi•error•[E0106]: missing lifetime specifier, indicates that you are missing a named lifetime parameter in your code. The error message also provides the location of the error, which is src/main.rs on line 5.

To fix this error, you need to add a named lifetime parameter to the function signature. Here's an example of how you can do that:

fn dangle<'a>() -> &'a i32 {
    // Function body
}

In this example, the named lifetime parameter 'a is added to the function signature. This indicates that the returned reference will have the same lifetime as the input parameter or any other references it depends on.

By adding the named lifetime parameter, you should be able to resolve the missing lifetime specifier error.
