String's lifetime when returning Vec<&str> [duplicate]

Answer 1

A &'static str is a string literal e.g. let a : &'static str = "hello world". It exists throughout the lifetime of the application.

If you're creating a new String, then that string is not static!

Simply return a vector of String.

fn foo() -> Vec<String> {

    let mut vec = Vec::new();
    let mut string = String::new();

    // doing something with string...

    vec.push(string);

    return vec;
}

fn main() {
    foo();
}
