如何匹配正则表达式，但返回Rust Nom中输入的剩余部分？

[dependencies]
nom = "6.2.1"

use nom::{
    bytes::complete::take_while,
    character::complete::char,
    sequence::tuple,
    IResult,
};

fn parse_input(input: &str) -> IResult<&str, &str> {
    tuple((take_while(|c: char| c.is_alphanumeric()), take_while(|c: char| !c.is_alphanumeric())))(input)
}

fn main() {
    let input = "abc123xyz";
    match parse_input(input) {
        Ok((remaining, result)) => {
            println!("Matched: {}", result);
            println!("Remaining: {}", remaining);
        }
        Err(e) => println!("Error: {:?}", e),
    }
}
