rust - Split a string and return Vec<String>

Question

I want to split a string and return Vec<String> from my function. It has to be Vec<String> and not Vec<&str> because I can't return Vec<&str>, can I? If I can, though, how can I do that?

let var1: Vec<&str> = my_string.split("something").collect();
let res = var1.iter().map(|x| x.to_string());
// I want to return Vec<String>

I've tried different versions but gotten error: mismatched types and other kinds of similar errors. Is there an easier way?

You don't need to create an intermediate Vec<&str>, just map to_string() and use collect() after that:

let res: Vec<String> = my_string.split("something").map(|s| s.to_string()).collect();
