Function elm_space_ref

pub fn elm_space_ref<'a, I>() -> Parser<'a, I, &'a I>
where
    I: Element + PartialEq + 'a,

Returns a Parser that parses the space (’ ’, ‘\t’). (for reference)
スペース(’ ’, ‘\t’)を解析するParserを返します。(参照版)

Example

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

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

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

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

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