Function successful_lazy

pub fn successful_lazy<'a, I, A, F>(f: F) -> Parser<'a, I, A>
where
    I: 'a,
    F: Fn() -> A + 'a,
    A: 'a,

Returns a Parser representing the successful parsing result.
成功した解析結果を表すParserを返します。

• f: a closure that returns the parsed result value.
• f: 解析結果の値を返すクロージャ

Example

use oni_comb_parser_rs::prelude::*;

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

let parser: Parser<char, char> = successful_lazy(|| 'a');

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

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