Function take_until1

Source 
pub fn take_until1<T, Input, Error>(tag: T) -> impl Fn(Input)
where
    Error: ParseError<Input>,
    Input: InputTake + FindSubstring<T>,
    T: InputLength + Clone,
Available on crate feature mtls only.
Expand description

Returns the non empty 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_until1;

fn until_eof(s: &str) -> IResult<&str, &str> {
  take_until1("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")));
assert_eq!(until_eof("eof"), Err(Err::Error(Error::new("eof", ErrorKind::TakeUntil))));
