Function winnow::bytes::streaming::take_till

pub fn take_till<T, I, Error: ParseError<I>>(
    list: T
) -> impl Fn(I) -> IResult<I, <I as Stream>::Slice, Error>where
    I: Stream,
    T: ContainsToken<<I as Stream>::Token>,

👎Deprecated since 0.1.0: Replaced with <code>winnow::bytes::take_till0</code> with input wrapped in <code>winnow::Partial</code>

Returns the longest input slice (if any) 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).

Partial Specific

Partial version will return a ErrMode::Incomplete(Needed::new(1)) if the match reaches the end of input or if there was not match.

Example

use winnow::bytes::streaming::take_till;

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

assert_eq!(till_colon("latin:123"), Ok((":123", "latin")));
assert_eq!(till_colon(":empty matched"), Ok((":empty matched", ""))); //allowed
assert_eq!(till_colon("12345"), Err(ErrMode::Incomplete(Needed::new(1))));
assert_eq!(till_colon(""), Err(ErrMode::Incomplete(Needed::new(1))));

WARNING: Deprecated, replaced with winnow::bytes::take_till0 with input wrapped in winnow::Partial
