Arrange phrase based on numbers inside each word

pub fn arrange_phrase(phrase: &str) -> String {
    // split phrase by whitespace
    let split = phrase.split_whitespace();

    // create a "pairs" data structure which is a vector of Strings.
    let mut pairs: Vec<(i32, String)> = vec![];

    // loop over split words to build the pairs list.
    for word in split {
        // loop over the word and extract the numeric string, using it as a "key" to the tupele in the tuple list.
        for ch in word.chars() {
            if ch.is_numeric() {
                let num = ch.to_string().parse::<i32>().unwrap();
                let new_word = word.replace(ch, "");
                pairs.push((num, new_word));
                break;
            }
        }
    }

    pairs.sort();

    let mut result: String = String::new();

    for tup in pairs {
        result.push_str(&tup.1);
        result.push(' ')
    }
    result = result.trim().to_string();

    result
}
