1 - Fails to compile.rs

//Transform iterable collection of Strings to iterable collection of &str and pass to libMain()
fn main() {
    xargo_lld_wrapper::libMain(std::env::args().map(|el| el.as_str()).collect::<Vec<_>>());
}

2 - Simplified code.rs

fn main() {
    let strings = vec!["string1".to_string(), "string2".to_string(), "string3".to_string()];
    let strs = strings.iter().map(|el| el.as_str()).collect::<Vec<_>>(); //lifetime violation (el), but not really (strings)
    let () = strs[1];
    println!("{:?}", strs);
}

3 - Will it Blend.rs

fn main() {
    xargo_lld_wrapper::lib_main(std::env::args().collect::<Vec<_>>()
                                                .iter()
                                                .map(|el| el.as_str()).collect::<Vec<_>>());
}
