Convert Vec into a slice of &str in Rust?

by

You can create a function that accepts both &[String] and &[&str] using the AsRef trait:

fn test<T: AsRef<str>>(inp: &[T]) {
    for x in inp { print!("{} ", x.as_ref()) }
    println!("");
}

fn main() {
    let vref = vec!["Hello", "world!"];
    let vown = vec!["May the Force".to_owned(), "be with you.".to_owned()];
    test(&vref);
    test(&vown);
}
