pub fn take_till<F, Input, Error: ParseError<Input>>(
cond: F
) -> impl Fn(Input) -> IResult<Input, Input, Error> where
Input: InputTakeAtPosition,
F: Fn(<Input as InputTakeAtPosition>::Item) -> bool, Expand description
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).
Example
use nom::bytes::complete::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"), Ok(("", "12345")));
assert_eq!(till_colon(""), Ok(("", "")));
