Function winnow::bytes::streaming::take_until
source · pub fn take_until<T, I, Error: ParseError<I>>(
tag: T
) -> impl Fn(I) -> IResult<I, <I as Stream>::Slice, Error>where
I: Stream + FindSlice<T>,
T: SliceLen + Clone,👎Deprecated since 0.1.0: Replaced with <code>winnow::bytes::take_until0</code> with input wrapped in <code>winnow::Partial</code>
Expand description
Returns the input slice up to the first occurrence of the pattern.
It doesn’t consume the pattern.
Partial Specific
Partial version will return a ErrMode::Incomplete(Needed::new(N)) if the input doesn’t
contain the pattern or if the input is smaller than the pattern.
Example
use winnow::bytes::streaming::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(ErrMode::Incomplete(Needed::Unknown)));
assert_eq!(until_eof("hello, worldeo"), Err(ErrMode::Incomplete(Needed::Unknown)));
assert_eq!(until_eof("1eof2eof"), Ok(("eof2eof", "1")));WARNING: Deprecated, replaced with winnow::bytes::take_until0 with input wrapped in winnow::Partial
