Function winnow::character::streaming::char

pub fn char<I, Error: ParseError<I>>(
    c: char
) -> impl Fn(I) -> IResult<I, char, Error>where
    I: Stream,
    <I as Stream>::Token: AsChar,

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

Recognizes one character.

Partial version: Will return Err(winnow::error::ErrMode::Incomplete(_)) if there’s not enough input data.

Example

fn parser(i: &str) -> IResult<&str, char> {
    char('a')(i)
}
assert_eq!(parser("abc"), Ok(("bc", 'a')));
assert_eq!(parser("bc"), Err(ErrMode::Backtrack(Error::new("bc", ErrorKind::Char))));
assert_eq!(parser(""), Err(ErrMode::Incomplete(Needed::new(1))));

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