pub fn take_until1<T, Input, Error>(tag: T) -> impl Fn(Input)
Available on crate feature

only.Expand description
Returns the non empty input slice up to the first occurrence of the pattern.
It doesn’t consume the pattern.
§Streaming Specific
Streaming version will return a Err::Incomplete(Needed::new(N))
if the input doesn’t
contain the pattern or if the input is smaller than the pattern.
§Example
use nom::bytes::streaming::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::Incomplete(Needed::Unknown)));
assert_eq!(until_eof("hello, worldeo"), Err(Err::Incomplete(Needed::Unknown)));
assert_eq!(until_eof("1eof2eof"), Ok(("eof2eof", "1")));
assert_eq!(until_eof("eof"), Err(Err::Error(Error::new("eof", ErrorKind::TakeUntil))));
