Function `tuple`

fn tuple<I, O, E: ParseError<I>, List: Tuple<I, O, E>>(l: List) -> impl FnMut(I) -> crate::internal::IResult<I, O, E>

Applies a tuple of parsers one by one and returns their results as a tuple. There is a maximum of 21 parsers

# use nom::{Err, error::ErrorKind};
use nom::sequence::tuple;
use nom::character::complete::{alpha1, digit1};
let mut parser = tuple((alpha1, digit1, alpha1));

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