Function take_till1

pub fn take_till1<F, I, Error: ParseError<I>>(
    cond: F,
) -> impl FnMut(I) -> IResult<I, I, Error>
where
    I: Input,
    F: Fn(<I as Input>::Item) -> bool,

Returns the longest (at least 1) input slice till a predicate is met.

The parser will return the longest slice till the given predicate (a function that takes the input and returns a bool).

It will return Err(Err::Error((_, ErrorKind::TakeTill1))) if the input is empty or the predicate matches the first input.

Example

use nom::bytes::complete::take_till1;

fn till_colon(s: &str) -> IResult<&str, &str> {
  take_till1(|c| c == ':')(s)
}

assert_eq!(till_colon("latin:123"), Ok((":123", "latin")));
assert_eq!(till_colon(":empty matched"), Err(Err::Error(Error::new(":empty matched", ErrorKind::TakeTill1))));
assert_eq!(till_colon("12345"), Ok(("", "12345")));
assert_eq!(till_colon(""), Err(Err::Error(Error::new("", ErrorKind::TakeTill1))));
