pub fn take_until<T, Input, Error>(tag: T) -> impl Fn(Input)

Expand description

Returns the input slice up to the first occurrence of the pattern.

It doesn’t consume the pattern. It will return Err(Err::Error((_, ErrorKind::TakeUntil))) if the pattern wasn’t met.

§Example

use nom::bytes::complete::take_until;

fn until_eof(s: &str) -> IResult<&str, &str> {
  take_until("eof")(s)
}

assert_eq!(until_eof("hello, worldeof"), Ok(("eof", "hello, world")));
assert_eq!(until_eof("hello, world"), Err(Err::Error(Error::new("hello, world", ErrorKind::TakeUntil))));
assert_eq!(until_eof(""), Err(Err::Error(Error::new("", ErrorKind::TakeUntil))));
assert_eq!(until_eof("1eof2eof"), Ok(("eof2eof", "1")));
