§Example

use std::iter::FromIterator;
use oni_comb_parser_rs::prelude::*;

let text: &str = "xyz";
let input = text.chars().collect::<Vec<_>>();

let parser: Parser<char, String> = none_ref_of("abc").of_many1().map(String::from_iter);

let result: ParseResult<char, String> = parser.parse(&input);

assert!(result.is_success());
assert_eq!(result.success().unwrap(), text);
