Macro shrimple_parser::call

macro_rules! call {
    ($($args:tt)*) => { ... };
}

Generates a closure that calls a function with a tuple’s contents as it arguments. The input can be anything as long as the last token contains all the arguments parenthesized.

use shrimple_parser::{Parser, parse_until_exact, call};

fn len_sum(a: &str, b: &str) -> usize {
    a.len() + b.len()
}

let input = "abc|def|";
let res = parse_until_exact("|")
    .and(parse_until_exact("|"))
    .map(call!(len_sum(a, b)))
    (input);
assert_eq!(res, Ok(("", 6)))
