Can someone give me a hand, I'm getting the following lifetime error: error: clean_number does not live long enough
Short url: http://is.gd/VIzHMS This is the code: #![feature(phase)] #[phase(plugin)] extern crate regex_macros; extern crate regex; use regex::Regex; static ALPHA_REGEX: Regex = regex!(r"[a-zA-Z]"); static NUMBER_REGEX: Regex = regex!(r"[^0-9]"); fn main() { let number = number("ads(123) 456-7890"); println!("{}", number); } fn number<'a>(number: &'a str) -> &'a str { let clean_number = clean(number); clean_number } fn clean<'a>(number: &'a str) -> &'a str { if ALPHA_REGEX.is_match(number) { "0000000000"; } let clean_number: String = NUMBER_REGEX.replace(number, ""); return clean_number.as_slice(); }
