何もしないParserを返します。unit()のエイリアスです。

Example

use oni_comb_parser_rs::prelude::*;

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

let parser: Parser<char, ()> = empty();

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

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