Function gchemol_parser::parsers::tuple

pub fn tuple<I, O, E, List>(l: List) -> impl Fn(I) where
    E: ParseError<I>,
    I: Clone,
    List: Tuple<I, O, E>, 

applies a tuple of parsers one by one and returns their results as a tuple

use nom::character::complete::{alpha1, digit1};
let parser = tuple((alpha1, digit1, alpha1));

assert_eq!(parser("abc123def"), Ok(("", ("abc", "123", "def"))));
assert_eq!(parser("123def"), Err(Err::Error(("123def", ErrorKind::Alpha))));
